Interstate 10 (I-10), a major transcontinental Interstate Highway in the Southern United States, runs across the southern part of Louisiana for {{convert|274.42|mi|km}}{{google maps |url = https://maps.google.com/maps?saddr=I-10+(Western+Terminus)&daddr=29.9537133,-90.083842+to:I-10+(Eastern+Terminus)&hl=en&ll=30.183122,-91.642456&spn=2.616164,5.410767&sll=30.334954,-91.565552&sspn=2.612124,5.410767&geocode=FfC0ywEdCztq-g%3BFbEOyQEd_m2h-il9-67U56UghjF7kRhLjiO7tQ%3BFYtkzgEdsC2o-g&mra=mrv&via=1&t=m&z=8 |title = Overview Map of I-10 |access-date = June 2, 2013 }} from Texas to Mississippi. It passes through Lake Charles, Lafayette, and Baton Rouge, dips south of Lake Pontchartrain to serve the New Orleans metropolitan area, then crosses Lake Pontchartrain and leaves the state.

Route description

I-10 enters Louisiana at the state's southwestern corner from Orange, Texas, in a concurrency with US Route 90 (US 90), which leaves the freeway at the first exit. The two routes closely parallel each other through much of the state. The first community I-10 approaches in the state is Vinton, Louisiana. Between Sulphur and Lake Charles there is an interchange with I-210. I-10 crosses the Calcasieu River Bridge into Lake Charles, passing north of the center of town, before meeting the western end of I-210. Between Lake Charles and Lafayette, I-10 bypasses several small towns including Iowa, Welsh, Jennings, and Crowley. In Lafayette, I-10 meets the current southern terminus of I-49, leaving northwest out of the city and passing by the community of Breaux Bridge.

From Lafayette, the highway heads east-northeast toward Baton Rouge via the Atchafalaya Swamp Freeway, an {{convert|18.2|mi|km|adj=on}} bridge across the Atchafalaya River and its accompanying swamp. Between the two cities, I-10 parallels US 190, from Opelousas to Baton Rouge. This route has signs and is designated as an alternate I-10 bypass that runs from I-10/I-49 north to US 190 (exit 19B at Opelousas) then east across to Baton Rouge and back down to I-10 via I-110 south. Traffic can be diverted both ways along this route should there be the necessity to close I-10 across the Atchafalaya Swamp Freeway and is also used as a hurricane evacuation route.

In the capital of Baton Rouge, US 190 continues east alongside I-12 to Hammond and Slidell while I-10 turns southeastward and parallels US 61 (Airline Highway) to New Orleans. In the Crescent City, I-10 rejoins US 90 (and later US 11) as it heads toward Slidell. In Slidell, US 11 continues northeastward toward Hattiesburg, Mississippi while I-10 and US 90 turn eastward toward coastal Mississippi.

Major bridges on I-10 in Louisiana include the Sabine River Bridge (c. 1952, replaced 2003), the Lake Charles I-10 Bridge (1952), the Atchafalaya Swamp Freeway (1973), the Horace Wilkinson Bridge over the Mississippi River (1968), the Bonnet Carré Spillway Bridge (c. 1972), the Industrial Canal Bridge (c. 1960), Frank Davis "Naturally N'Awlins" Memorial Bridge (1965, replaced 2010), and the Pearl River Bridge (c. 1970).

History

File:New Orleans, Louisiana 1955 Yellow Book.jpg

By the beginning of planning for the Interstate Highway System in 1939 (then called the Interregional Highway System), the Houston–New Orleans–Mobile corridor was part of the system. Preliminary plans took it along US 90 all the way through Louisiana, serving Lake Charles and Lafayette but not Baton Rouge.{{cite map |author = Bureau of Public Roads |author-link = Bureau of Public Roads |url = https://commons.wikimedia.org/wiki/File:Interregional_Highway_plan_1939.jpg |title = Proposed Interregional Highway System |year = 1939 |scale = Scale not given |location = Washington, DC |publisher = Bureau of Public Roads |access-date = August 15, 2012 |via = Wikimedia Commons |archive-date = January 2, 2016 |archive-url = https://web.archive.org/web/20160102173240/https://commons.wikimedia.org/wiki/File:Interregional_Highway_plan_1939.jpg |url-status = live }} By c. 1943, it had been shifted to the north west of New Orleans, using the Louisiana Highway 12 (LA 12), US 190, and US 61 corridors, and serving Baton Rouge but not Lake Charles or Lafayette.{{cite map |author = Bureau of Public Roads |url = https://commons.wikimedia.org/wiki/File:Interregional_Highway_plan_ca_1943.jpg |title = Routes of the Recommended Interregional Highway System |year = c. 1943 |scale = Scale not given |location = Washington, DC |publisher = Bureau of Public Roads |access-date = August 15, 2012 |via = Wikimedia Commons |archive-date = January 30, 2016 |archive-url = https://web.archive.org/web/20160130235654/https://commons.wikimedia.org/wiki/File:Interregional_Highway_plan_ca_1943.jpg |url-status = live }} The 1947 plan shifted it to roughly the current alignment, including the long stretch of new corridor across the Atchafalaya Swamp.{{cite map |author = Public Roads Administration |author-link = Public Roads Administration |url = https://commons.wikimedia.org/wiki/File:Interstate_Highway_plan_August_2,_1947_big_text.jpg |title = National System of Interstate Highways |date = August 2, 1947 |scale = Scale not given |location = Washington, DC |publisher = Public Roads Administration |access-date = August 15, 2012 |via = Wikimedia Commons }} The corridor was assigned the I-10 designation in mid-1957.{{cite map |author = Public Roads Administration |url = https://commons.wikimedia.org/wiki/File:Interstate_Highway_plan_August_14,_1957.jpg |title = Official Route Numbering for the National System of Interstate and Defense Highways |date = August 14, 1957 |scale = Scale not given |location = Washington, DC |publisher = Public Roads Administration |access-date = August 15, 2012 |via = Wikimedia Commons |archive-date = July 19, 2017 |archive-url = https://web.archive.org/web/20170719213034/https://commons.wikimedia.org/wiki/File:Interstate_Highway_plan_August_14,_1957.jpg |url-status = live }}

Prior to the gaining of federal funding for the Interstate System in the late 1950s, a toll road, the Acadian Thruway, had been proposed between Lafayette and a point near Gramercy on Airline Highway (US 61). This would have provided a shorter route than I-10, bypassing Baton Rouge to the south. The Gramercy Bridge was later built along its planned alignment, with LA 3125 connecting to Gramercy, but no road extends west from the bridge across the Atchafalaya Swamp to Lafayette.

I-12, serving as a bypass of New Orleans around the north side of Lake Pontchartrain, was not added until October 17, 1957. At the time, I-10 and I-59 split in eastern New Orleans, with I-59 following present I-10 and I-10 following the US 90 corridor into Mississippi, and so I-12 only ran to I-59 north of Slidell.{{cite map |author = Public Roads Administration |url = https://commons.wikimedia.org/wiki/File:Interstate_Highway_plan_October_17,_1957_reverse_colors.jpg |title = Routes To Be Added to the National System of Interstate and Defense Highways |date = October 17, 1957 |scale = Scale not given |location = Washington, DC |publisher = Public Roads Administration |access-date = August 15, 2012 |via = Wikimedia Commons |archive-date = October 22, 2016 |archive-url = https://web.archive.org/web/20161022094425/https://commons.wikimedia.org/wiki/File:Interstate_Highway_plan_October_17,_1957_reverse_colors.jpg |url-status = live }} By the mid-1960s, the routes had been realigned to their current configuration, with I-12 and I-59 both ending at I-10 near Slidell.{{cite map |author = Public Roads Administration |url = https://commons.wikimedia.org/wiki/File:Interstate_Highway_status_unknown_date.jpg |title = The National System of Interstate and Defense Highways |year = c. 1963 |scale = Scale not given |location = Washington, DC |publisher = Public Roads Administration |access-date = August 15, 2012 |via = Wikimedia Commons |archive-date = November 9, 2012 |archive-url = https://web.archive.org/web/20121109213025/http://commons.wikimedia.org/wiki/File:Interstate_Highway_status_unknown_date.jpg |url-status = live }}

Construction of the Interstate Highway System in Louisiana began in 1957.{{cite news |title = Federal funds for roads |newspaper = State-Times |location = Baton Rouge |date = August 7, 1957 |page = 8A }} Early I-10 contracts were done under the route designation LA 3027. Much of the early construction on the I-10 corridor was concentrated on relieving traffic problems in urban centers. Several such projects were already underway and were incorporated into the route of I-10 during construction, such as the Pontchartrain Expressway in New Orleans. In addition, the two major bridges on the route in Calcasieu Parish between the Texas state line and Lake Charles were built for US 90 in the early 1950s and retrofitted for I-10 traffic. Sections of I-10 through rural areas and/or those sections already served adequately by existing highways, such as Airline Highway (US 61) between Baton Rouge and New Orleans, were constructed later in the program. By the spring of 1975, the entire route of I-10 had been opened across Louisiana except for a problem {{convert|5.5|mi|km|adj=on}} section between Gonzales and Sorrento that was not completed for another three years.

Reconstruction of the portion at the I-610 Split vicinity was undertaken in the late 1990s. Also in the late 1990s, further work was done on the expressway as two ramps were constructed, connecting West I-10 to West Business U.S. 90 and westbound Claiborne Avenue (West US 90), replacing an earlier, more dangerous ramp. The direct ramp from 90B East to I-10 East was completed by 1989.{{cite news |last=Philbin |first=Walt |title=I-10's Deadly Ramps a Worry from the Start |newspaper=The Times-Picayune |issn=1055-3053 |location=New Orleans |date=March 8, 1989 |page=A1}}

In the aftermath of Hurricane Katrina, the I-10 Twin Span Bridge, a portion of I-10 between New Orleans and Slidell, spanning the eastern end of Lake Pontchartrain, was severely damaged, causing a break in I-10 at that point. Unlike the Escambia Bay Bridge (east of Pensacola, Florida and damaged by Hurricane Ivan), which is a major artery, I-12 is available to bypass New Orleans. Taking I-12 to the Lake Pontchartrain Causeway allowed entry and exit to and from the Greater New Orleans area from the East. On October 14, 2005, at 3:00 pm, the eastbound span was reopened to two way traffic.

In 2022, the Calcasieu River Bridge turned 70 years old. With over 600,000 bridges, the average bridge age in the United States is 42 years old, with one in nine rated as deficient.

Auxiliary routes

File:Horace Wilkinson Bridge southeast.jpg in Baton Rouge over the Horace Wilkinson Bridge]]

A previous I-310 was added in 1964 and canceled in 1969. It would have run from I-10 east of downtown New Orleans south and southwest through the French Quarter to the Greater New Orleans Bridge.
The first I-410 was a northern bypass of Baton Rouge along the Airline Highway (US 61/US 190) corridor. It was added in September 1955 and removed by the late 1960s.
The second I-410 was defined in 1969 as a southern bypass of New Orleans, as a sort of replacement for the canceled I-310. The southern section of I-410 was canceled in 1977, and the west and east legs became I-310 and I-510, respectively.
I-510 is a spur from I-10 in eastern New Orleans south to the Paris Road Bridge over the Gulf Intracoastal Waterway (Mississippi River-Gulf Outlet Canal). It was part of a longer I-410 from 1969 to 1977.
I-610 is a bypass for through traffic north of downtown New Orleans. It was added in September 1955.
I-910 is a piece of future I-49 from downtown New Orleans south and west to Marrero. The temporary designation was assigned by the Federal Highway Administration and American Association of State Highway Officials in 1999, but is not signed and has not been accepted by the Louisiana Department of Transportation and Development.
