Massachusetts Turnpike

The Massachusetts Turnpike is informally divided into two sections by MassDOT: the original {{convert|123|mi|km|adj=on}} "Western Turnpike" extending from the New York state border through the interchange with I-95 and Route 128 at exit 123 in Weston, and the {{convert|15|mi|km|adj=on}} "Boston Extension" that continues beyond exit 123 through Boston.{{cite web |url = http://www.massdot.state.ma.us/Portals/0/docs/infoCenter/financials/RefinanceTR_Study_042710.pdf |title = Massachusetts Turnpike: Metropolitan Highway System |author = Cambridge Systematics |publisher = Massachusetts Department of Transportation |date = January 28, 2010 |access-date = June 19, 2017 |archive-url = https://web.archive.org/web/20151020221146/http://www.massdot.state.ma.us/Portals/0/docs/infoCenter/financials/RefinanceTR_Study_042710.pdf |archive-date = October 20, 2015 |url-status = dead }} It is a four-lane highway from the New York state border through its interchange with I-84 at exit 78 in Sturbridge; it expands to six lanes beyond this interchange and briefly travels with eight lanes from exit 127 in Newton through exit 133 by the Prudential Center in Boston.

After almost {{Convert|50|mi|km}} of relative ruralness, I-90 has an interchange that leads to the separate routes of I-91 and US 5 at exit 45 in West Springfield; it passes over the Connecticut River before reaching Route 33 at exit 49 and I-291 at exit 51, both in Chicopee. The turnpike passes through Ludlow at exit 54 before crossing the Quaboag River to exit 63 in Palmer. The turnpike first enters Worcester County in Sturbridge, where exit 78 serves as the eastern terminus of I-84.{{cite web |url = http://www.massdot.state.ma.us/Portals/8/docs/maps/StateMap2016.png |title = Official Massachusetts Transportation Map |publisher = Massachusetts Department of Transportation |access-date = June 21, 2017 |archive-url = https://web.archive.org/web/20180624204402/http://www.massdot.state.ma.us/Portals/8/docs/maps/StateMap2016.png |archive-date = June 24, 2018 |url-status = dead }} In Auburn, exit 90 has a two-Interstate interchange with I-395 traveling southbound and I-290 traveling eastbound. The Blackstone River flows underneath the turnpike in Millbury, where it has an interchange with Route 146 and a second direct connection to US 20 at exit 94. Entering Middlesex County in Hopkinton, it has an interchange with I-495 at exit 106. The turnpike crosses the Sudbury River between exit 111 at Route 9 and exit 117 at Route 30, all located within Framingham. The last connection with another Interstate Highway on the Western Turnpike is located in Weston, at the I-95 and Route 128 concurrency.

This exit is also used to access Soldiers Field Road, a surface parkway that provides local access through central Boston and parallels the Turnpike. Before being renumbered exit 131 in both directions, exit 18 was a left-hand eastbound exit and westbound entrance, and exit 20 was a westbound exit and eastbound entrance; a mainline toll plaza was previously placed in between them for through traffic and was classified as "exit 19". Past the tolls, the turnpike reduces to six lanes, heads through the campus of Boston University and passes Fenway Park before crossing over the Muddy River as it approaches the city's central neighborhoods.

Exit 133 and the now-closed Clarendon Street onramp are located within the Prudential Tunnel, which takes the turnpike underneath the Prudential Center;{{cite web |url = http://www.bostonherald.com/news/local_coverage/2017/03/man_killed_as_car_goes_airborne_in_pru_tunnel |title = Man killed as car goes airborne in Pru tunnel |last = Sweet |first = Laurel |newspaper = Boston Herald |date = March 26, 2017 |access-date = June 22, 2017 |archive-date = June 8, 2017 |archive-url = https://web.archive.org/web/20170608071407/http://www.bostonherald.com/news/local_coverage/2017/03/man_killed_as_car_goes_airborne_in_pru_tunnel |url-status = live }} the former is an eastbound exit towards the Prudential Center and Copley Square, while the latter is a westbound-only entrance from Clarendon Street.

In the November 9, 2006, edition of The Boston Globe, Governor Mitt Romney announced his intention to try to remove the tolls before his successor, Deval Patrick, was inaugurated in January 2007, but this did not occur. In 2008, Patrick announced a similar plan to remove most tolls west of I-95,{{Cite news |url = https://www.metrowestdailynews.com/article/20081110/NEWS/311109882 |title = Patrick Planning to Dismantle Mass.

State law requires tolls to be removed west of Route 128 when its debt is paid and the road is in "good condition", but MassDOT plans to continue tolls after the bonds are paid off in January 2017, because the road will still need $135 million per year for repairs and maintenance.{{update inline|date=January 2020}}

At a January 22, 2009, board meeting, the turnpike decided to stop charging a one-time $25.95 fee for the acquisition of a Fast Lane toll transponder, replacing it with a 50-cent monthly recurring service fee.

When all-electronic tolling went live on the Mass Pike in 2017, the Tobin Bridge, Callahan Tunnel, Sumner Tunnel, and Ted Williams Tunnel joined the system and were converted to charging a single toll in both directions, rather than a double toll in one direction. The Tobin Bridge was converted to all-electronic tolling for southbound only in July 2014.

In the period following World War II, Boston had fallen into a deep period of stagnant growth. Its former maritime industries had closed as traffic in the harbor declined, the textile mills that had provided a large portion of the city's wealth had migrated out of the region seeking new locations that would allow them to maximize revenues, and property development had ground to a halt with virtually no new construction of any impact occurring since the beginning of the Great Depression.{{cite book |last1 = Tsipis |first1 = Yanni |year = 2002 |title = Building the Mass Pike |location = Mount Pleasant, South Carolina |publisher = Arcadia Publishing |isbn = 0738509728 |url = https://archive.org/details/buildingmasspike00yann |pages = 9–10 }} Boston retail stalwarts such as Filene's and Jordan Marsh had decided to focus their energies and growth into the suburbs; Boston's citizens had begun to flee to the same suburban pastures as property taxes in the city skyrocketed.

After the end of the war, Massachusetts entered into a period of new highway projects planning that sought to help end the economic malaise the state was suffering from. It was in 1947 that Republican Governor Robert F. Bradford realized that the commonwealth needed to implement a standard framework to properly guide the planning and construction of these new roadways. He commissioned a study to produce a new Highway Master Plan for the eastern region, and, by 1948, it had been completed. Seeking the political benefits that a major public works project would bring, Bradford sent his plan to the Democratic-controlled Massachusetts General Court for approval; however, the Democrats sat on the project until their candidate, newly elected Democratic Governor Paul A. Dever, took office in January 1949.{{harvp|Tsipis|2002|pp=7–8}}.

It was instead Dever who initiated the program to implement the Highway Master Plan for the city shortly after taking office in 1949. Enjoying a Democratic majority within the State House coupled with a Democratic governor for the first time in the commonwealth's history, he pushed through a series of highway bills with associated gas tax increases totaling over $400 million (equivalent to ${{Formatprice|{{inflation|US-GDP|400000000|1952}}}} in {{Inflation/year|index=US-GDP}}{{Inflation/fn|index=US-GDP}}) between 1949 and 1952.{{cite news |title = Baystate Notes Spending Record |work = The New York Times |date = November 5, 1958 }}{{page needed|date=August 2015}} To oversee this undertaking, Dever brought in the former commissioner of the Massachusetts Department of Public Works, William F. Callahan, to once again head the agency he had helmed from 1934 to 1939. Known for his strong personality and drive to get projects completed, Callahan immediately set out to construct three of the proposed highways (not including what would become I-495, which had been included in the 1947 plan): the "original outer" circumferential highway which became Route 128, the Southeast Expressway, and the Central Artery through the heart of the Boston's downtown. These three projects, totaling more than $92 million (equivalent to ${{Formatprice|{{inflation|US-GDP|92000000|1947}}}} in {{Inflation/year|index=US-GDP}}{{Inflation/fn|index=US-GDP}}), were seen as being essential to the growth of the city in the future. However, the construction of these roads took such a large portion of funds that the commonwealth was unable to provide funds for the Western Expressway project. However, before Callahan could oversee the completion of the southern leg of Route 128, he was appointed by Dever to run the newly formed MTA.{{cite book |last1 = Tsipis |first1 = Yanni |year = 2003 |title = Building 128 |location = Mount Pleasant, South Carolina |publisher = Arcadia Publishing |isbn = 0738511633 |url = https://archive.org/details/buildingroute12800tsip |pages = 8–9 }}{{harvp|Tsipis|2002|pp=27–28}}.

Because of the financial strain created by the bond issues used to construct these other highways, the commonwealth was unable to afford the costs of floating more bonds to fund the expenditures required to construct the Western Expressway along the Western Approach corridor of Boston. Callahan suggested creating a strong, independent, and semipublic transportation authority that could fund the new expressway by floating its own bond issues and financing them through tolls along the highway while having its own powers of eminent domain to secure the land needed to build it. Utilizing the political goodwill he accrued during his tenure as public works commissioner, primarily through extensive patronage hires, Callahan was able to push his idea for the new authority through the State House with ease.{{harvp|Berkman|1998|pp=180–181}} The authority was formed in early 1952, and, by 1955, it had issued the required bonds needed to construct a {{convert|123|mi|km|adj=on}} highway from the New York–Massachusetts border to the recently completed Route 128 in Weston. Despite being completed in 1957, many within the commonwealth quickly realized that the local routes used to get into Boston were still insufficient for the automotive traffic burdens placed upon them.{{harvp|Tsipis|2002|pp=27–29}}.

The road was designated as part of the Interstate Highway System as I-90 in 1959.{{cn|date=January 2025}} In 1964, exit numbers were introduced.{{cite news |url = https://www.bostonmagazine.com/news/2016/04/08/massachusetts-highway-exit-numbers-massdot/ |title = Many Massachusetts Highway Exit Numbers Could Soon Change |last = Clauss |first = Kyle Scott |work = Boston Magazine |date = April 8, 2016 |access-date = June 28, 2018 |archive-date = June 29, 2018 |archive-url = https://web.archive.org/web/20180629102251/https://www.bostonmagazine.com/news/2016/04/08/massachusetts-highway-exit-numbers-massdot/ |url-status = live }}

While the highway construction boom proved to be fortunate for the suburban communities these new roadways passed through, the economy of Boston was still in a fragile state.{{cite book |last1 = Kennedy |first1 = Lawrence |year = 1994 |title = Planning the City Upon a Hill: Boston Since 1630 |edition = 3rd |location = Boston |publisher = University of Massachusetts Press |isbn = 0870239236 |page = 168 }} Realizing that Boston still needed to be connected to the turnpike to help reverse its flagging economy and reputation as a municipal has-been, Callahan was tasked in 1955 by the legislature to create an extension into the city designed to facilitate a turnaround of the city's fortunes. This new highway would connect the Massachusetts Turnpike to the heart of the city with a {{Convert|12.3|mi|km|adj=on}} extension of the Interstate. It was his plan to bring the tolled turnpike from its terminus at Route 128 in West Newton into the city along the path of the Boston and Albany Railroad and connect it to the Southeast Expressway. This plan was in line with the 1948 Master Highway Plan for the city, which had always called for a Western Expressway to be built into the city. However, with the passage of the Federal-Aid Highway Act of 1956, the federal government provided sufficient funds to the states to construct new highways with a 90-percent subsidy, rendering the need for a toll road into the city obsolete.{{harvp|Tsipis|2002|pp=47–48}}. Complicating the matter, Callahan's planned extension route was not universally accepted by others within the state, such as newly elected Governor John A. Volpe and Newton Mayor Donald Gibbs, who sought to construct a freeway that would follow a different route between the Borders of Newton, Waltham, and Watertown along the Charles River and US 20 and be constructed using the funds now being provided by the Federal Highway Administration (FHWA).Britten{{full citation needed|date=August 2015}} Additionally, residents of the city of Newton, who would see significant demolition of neighborhoods within the city along with large portions of its central business district to make way for the turnpike extension, were adamantly against the proposed Boston and Albany routing of the road.{{harvp|Berkman|1998|pp=170–173}} Newton, through the terms of two mayors, set about fighting the turnpike proposal through a series of increasingly futile legislative maneuvers in the General Court. Realizing that the needs and wants of the smaller city could not overcome the influence of Callahan within the state capitol, the smaller city would instead redirect its efforts to blocking the highway at the federal level through the Interstate Commerce Commission (ICC) and federal courts.{{harvp|Berkman|1998|pp=177–181}} Affected property owners within Boston who were also looking at the possibility of losing their homes and business followed Newton's lead by filing a series of state and federal lawsuits that they hoped would derail the proposed extension.Fenton{{full citation needed|date=August 2015}} In the late 1950s, eminent domain takings for the Massachusetts Turnpike Extension into Boston devastated the historic Black-American community named "The Village". Compensation was offered for the homes below market value. Homeowners and renters confronted racial discrimination when trying to purchase or rent homes in Newton. Real estate agents would not work with them. They had to rely on word of mouth to find a new home. It is estimated that 50 percent left Newton as a result of the construction of the turnpike.{{Cite web |url = https://newton.wickedlocal.com/news/20170228/african-american-community-of-newton-has-long-legacy |title = African-American community of Newton has long legacy |first = Laura |last = Lovett |website = Newton TAB |access-date = December 11, 2020 |archive-date = January 22, 2021 |archive-url = https://web.archive.org/web/20210122191736/https://newton.wickedlocal.com/news/20170228/african-american-community-of-newton-has-long-legacy |url-status = live }}

Exit 11A (now exit 106) in Hopkinton opened in 1969. It was built to connect the turnpike with I-495 and enables transit between northern New England and Cape Cod.

The year 1968 saw the beginning of the first major improvement of the turnpike after the completion of the Boston extension in 1965. While the original design of the roadway called for an eight-lane expressway along the majority of the route, it was only constructed as a four-lane roadway along most of its length until it reached the junction of Route 9 in Framingham, where the roadway expanded to six lanes. Starting in 1968, the highway from the I-84 interchange in Sturbridge to Route 9 was widened from its original four lanes to six; that widening project was completed around 1971. However, the mainline right-of-way was constructed to allow future expansion of the roadway, with most bridges over the highway built with the eight-lane roadway in mind, so few bridges had to be rebuilt when it was widened in the late 1960s.

The original logo depicted Paul Revere on horseback with the words "Massachusetts Turnpike Authority" in a circle around him. One incarnation of the pilgrim hat shield had a Native-American arrow sticking through the pilgrim hat. It was replaced with a plain pilgrim hat and the words "Mass Pike" in 1989. It has been reported variously that the sign was changed due to confusion among motorists who sometimes mistakenly turned in the direction the arrow pointed (right) when attempting to enter the turnpike{{cite news |url = https://www.proquest.com/docview/294569430 |title = Redrawing the Native American Image |last = Montgomery |first = M.

Electronic toll collection was introduced as an alternative to cash payment with Fast Lane transponders in 1998; when installed in the inner windshield of a vehicle, the equipment would be recognized automatically in special lanes at toll plazas and would withdraw the toll amount from the motorist's account.{{cite web |url = http://blogs.wickedlocal.com/massmarkets/2012/05/10/massachusetts-pulls-out-of-the-fast-lane-in-favor-of-e-zpass/ |title = Massachusetts pulls out of the Fast Lane in favor of E-ZPass |last = Chesto |first = Jon |publisher = Wicked Local |date = May 10, 2012 |access-date = June 22, 2017 |url-status = dead |archive-url = https://web.archive.org/web/20170611105736/http://blogs.wickedlocal.com/massmarkets/2012/05/10/massachusetts-pulls-out-of-the-fast-lane-in-favor-of-e-zpass/ |archive-date = June 11, 2017 |df = mdy-all }}

Exit 94 (former exit 10A) in Millbury connects the turnpike to Route 146 and US 20 via the Route 20 Connector, which, in turn, facilitates movement between Worcester and Providence, Rhode Island; construction began in 1996 and was opened in 1998 before being completed in 1999.{{cite web |url = http://www.wrrb.org/wp-content/uploads/2014/07/03-03transport.pdf |title = Worcester's Link to the MassPike: An Update on the Route 146 Connector |publisher = Worcester Regional Research Bureau |date = May 15, 2003 |access-date = April 18, 2019 |archive-date = April 18, 2019 |archive-url = https://web.archive.org/web/20190418165945/http://www.wrrb.org/wp-content/uploads/2014/07/03-03transport.pdf |url-status = live }}

File:Boston Highway System Pre Post Big Dig.gif

When designing the Central Artery/Tunnel Project (CA/T Project; Big Dig) in the 1970s and 1980s, the horror stories regarding urban renewal projects such as the construction of the old viaduct in the 1950s weighed heavy on the minds of Frederick P. Salvucci and his team. It was realized early on that the commonwealth could not just lay waste to parts of the city and pave them over; the state would have to ensure that construction would balance the needs of the highways against the livability of the city and neighborhoods the project would pass through. Mitigation efforts would be of utmost importance in moving ahead with the project.DOT{{full citation needed|date=August 2015}}Altshuler, p. 95–96.{{full citation needed|date=August 2015}} Governor Francis Sargent had shut down any ideas of further freeway construction within the Route 128 beltway in 1970, thereby canceling both the I-695 "inner belt" and the Southwest Corridor freeway projects, placing more emphasis on the already-completed Boston extension of I-90, the extension of I-93 into Boston, and the work to eventually depress Boston's Central Artery below ground level as the only unbuilt freeway-related construction projects "inside" of Route 128 that would be allowed to go forward.{{Cite web |url = https://www.pbs.org/greatprojects/interviews/salvucci_6.html |title = Great Projects: The Building of America .

Salvucci deliberately planned to bring the East Boston Extension through areas with little or no occupancy or those properties already owned by the commonwealth. As a result, East Boston saw almost no takings of buildings or homes through eminent domain or the destruction of neighborhoods because construction was relegated to the then-unoccupied areas of the Seaport District and Logan International Airport. Like the first turnpike extension, the connection of the turnpike to East Boston was also designed to provide an economic stimulus to the city, this one to revitalize the desolate Seaport District. The MTA managed the Big Dig, which rerouted the elevated Central Artery into the O'Neill Tunnel through Downtown Boston, and extended the turnpike beyond its terminus at the Central Artery into the Ted Williams Tunnel and connected it to Route 1A beyond Logan International Airport. Construction began in 1991, and the final extension of the turnpike was opened in February 2003. It was for the financial needs of the project that the "Metropolitan Highway System" was created with the turnpike east of Route 128; the Ted Williams, Sumner, and Callahan tunnels under Boston Harbor; and I-93 from Southampton Street through the O'Neill Tunnel and the Zakim Bridge to the foot of the Tobin Bridge.{{cite web |url = http://www.mass.gov/legis/laws/mgl/81a-3.htm |title = MGL Chapter 81A, Section 3 |access-date = February 21, 2009 |archive-url = https://web.archive.org/web/20100726222848/http://www.mass.gov//legis/laws/mgl/81a-3.htm |archive-date = July 26, 2010 |url-status = dead }} Finances for the Western Turnpike and the Boston Extension continue to be handled separately with this reorganization.

By 2004, much of the road had been improved with renovated pavement, renovated bridges, and a jersey barrier in the median.

In response to a fatality caused by the collapse of the ceiling of the eastbound I-90 connector tunnel approaching the Ted Williams Tunnel on July 10, 2006, and, in response to MTA Chair Matthew J.

Brennan Jr. created the idea for this potential new exit in 1996, and he continued to advocate for the idea into the late 2000s.{{cite web |url = https://www.telegram.com/story/news/local/east-valley/2008/03/06/state-urged-to-consider-new/52514997007/ |title = State urged to consider new Pike exit |last = Lilyestrom|first = Betty|work = Telegram & Gazette|location= Worcester, Massachusetts|date = March 6, 2008 |access-date = February 26, 2023 |archive-date = February 26, 2023 |archive-url = https://web.archive.org/web/20230226070922/https://www.telegram.com/story/news/local/east-valley/2008/03/06/state-urged-to-consider-new/52514997007/ |url-status = live }}{{cite web |url = https://www.telegram.com/story/news/local/east-valley/2008/01/09/pike-entrance-proposal-for-route/52684034007/ |title = Pike entrance proposal for Route 56 resurrected |last = Lilyestrom|first = Betty|work = Telegram & Gazette|location= Worcester, Massachusetts|date = January 9, 2008 |access-date = February 26, 2023 |archive-date = February 26, 2023 |archive-url = https://web.archive.org/web/20230226070300/https://www.telegram.com/story/news/local/east-valley/2008/01/09/pike-entrance-proposal-for-route/52684034007/ |url-status = live }} In 2011, the Town of Oxford included the construction of a new interchange as a long-term recommendation in their municipal transportation plan; construction estimates were $60 million to $75 million (equivalent to ${{formatprice|{{inflation|US-GDP|65000000|2011}}}} to ${{formatprice|{{inflation|US-GDP|75000000|2011}}}} in {{inflation-year|US-GDP}}{{inflation-fn|US-GDP}}).{{cite web |url = https://www.oxfordma.us/sites/g/files/vyhlif4836/f/uploads/transportation_plan.pdf |title = Oxford Transportation Plan |last = |first = |work = Town of Oxford, Massachusetts|date = April 2011 |access-date = February 26, 2023 |archive-date = February 26, 2023|archive-url = https://web.archive.org/web/20230226071131/https://www.oxfordma.us/sites/g/files/vyhlif4836/f/uploads/transportation_plan.pdf|url-status = live }}

Since 2001, the MTA had come under fire from state politicians in a fight for control of the quasistate agency. Beginning in 2001, former Massachusetts acting Governor Jane Swift (Republican) attempted to fire Christy Mihos, a former turnpike board member and Jordan Levy, the vice chair of the board.

Mihos and Levy had cast votes on the board to postpone a toll hike. Swift objected, saying such a delay was "fiscally irresponsible" and saying the two men "interfered with the effective daily management of the Authority".{{cite web |url = http://caselaw.lp.findlaw.com/scripts/getcase.pl?court=ma&vol=sjcslip/sjcMay02h&invol=1 |title = Jordan Levy & another vs. the Acting Governor & another |access-date = July 13, 2007 |date = November 19, 2001 |archive-date = July 9, 2012 |archive-url = https://archive.today/20120709033612/http://caselaw.lp.findlaw.com/scripts/getcase.pl?court=ma&vol=sjcslip/sjcMay02h&invol=1 |url-status = live }} Mihos and Levy refused to step down and sued Swift to retain their positions. The SJC ruled that the turnpike was "not part of the machinery of the government" and therefore not subject to Swift's decisions.{{cite web |url = http://www.ma-appellatecourts.org/display_docket.php?dno=SJC-08730 |title = Jordan Levy & another vs. the Acting Governor & another SJC-08730 |access-date = July 2, 2007 |date = May 7, 2002 |archive-date = October 18, 2015 |archive-url = https://web.archive.org/web/20151018170403/http://www.ma-appellatecourts.org/display_docket.php?dno=SJC-08730 |url-status = live }}

Governor Mitt Romney, elected in 2002 during a fiscal crisis, ran on a political platform of streamlining state government and eliminating waste. Part of this was the elimination of the MTA. Romney wanted to fold the turnpike into the Massachusetts Highway Department (MassHighway), the state highway department, operated under the Executive Office of Transportation. A first step to this was to replace the chair of the board, Matthew J. Amorello, with someone loyal to the governor. The governor has the power to appoint members to the board, but the SJC advised in an advisory opinion that "nothing in G. L. c. 81A explicitly provides for the removal and reassignment of the chairperson to the position of 'member{{' "}}.{{cite web |url = http://www.socialaw.com/slip.htm?cid=15320&sid=120 |title = Answer of the justices to the governor. |access-date = July 2, 2007 |date = June 29, 2005 |archive-date = May 15, 2011 |archive-url = https://web.archive.org/web/20110515145652/http://www.socialaw.com/slip.htm?cid=15320&sid=120 |url-status = live }}{{cite web |url = http://www.ma-appellatecourts.org/display_docket.php?dno=SJC-09461 |title = Request for Advisory Opinion, A-108 SJC-09461 |access-date = July 2, 2007 |date = June 29, 2005 |archive-date = October 18, 2015 |archive-url = https://web.archive.org/web/20151018170403/http://www.ma-appellatecourts.org/display_docket.php?dno=SJC-09461 |url-status = live }}

Romney put pressure on Amorello to step down. Amorello announced he would do so in 2007, after Romney would have left office. Romney continued to press the legislature to give him the power to remove members from the board, specifically the chairman, pointing to a series of financial and construction mishaps over the last several years. However, the legislature instead sought to keep Amorello on board by extending the terms of various board members to prevent Romney from removing Amorello.{{cite news |url = http://www.boston.com/news/local/massachusetts/articles/2006/06/02/budget_amendment_in_senate_would_let_amorello_keep_job/ |title = Budget amendment in Senate would let Amorello keep job |date = June 2, 2006 |last = Murphy |first = Sean P. |work = The Boston Globe |access-date = August 21, 2008 |archive-date = June 14, 2006 |archive-url = https://web.archive.org/web/20060614114618/http://www.boston.com/news/local/massachusetts/articles/2006/06/02/budget_amendment_in_senate_would_let_amorello_keep_job/ |url-status = live }}

Under a plan to save state funds, the Massachusetts Registry of Motor Vehicles (RMV) announced plans to close eleven of its branches in leased locations and move the operations into facilities owned by MassHighway and the MTA located in toll plazas, visitor centers, and offices.
