Interstate 17

I-17 is known as the Black Canyon Freeway from the northern end of the Phoenix Metropolitan Area to a point {{convert|2.2|mi|km}} south of The Stack interchange with I-10 northwest of Downtown Phoenix. (It is accompanied by frontage roads for most of this portion, and they carry the Black Canyon Highway name to distinguish from the freeway status.) At the Durango Curve southwest of downtown, between the 19th Avenue and Buckeye Road interchanges, it picks up the designation Maricopa Freeway all the way to the southern terminus at the second I-10 junction. It is one of the metropolitan area's primary freeways.{{ADOT log|year=2013|accessdate=May 23, 2020}} It has two interchanges with I-10 in Phoenix.{{google maps |url=https://maps.google.com/maps?f=d&hl=en&geocode=2790773938709236001,33.427409,-112.042960%3B5160041869956207009,35.177317,-111.661367&saddr=I-17+N+%4033.427409,+-112.042960&daddr=35.177316,-111.661563&mra=dme&mrcr=0&mrsp=1&sz=15&sll=35.172966,-111.671391&sspn=0.015856,0.028925&ie=UTF8&ll=34.347971,-111.934204&spn=2.049897,3.691406&z=8 |title=Overview map of I-17 |access-date=February 15, 2008}}

The northwestern portion of Valley Metro's light rail line runs over a bridge of I-17 from Mountain View Road to Metro Parkway, serving one station at Metro Parkway.

I-17 ends at Milton Road (SR 89A) north of I-40 in Flagstaff.

The I-17 corridor roughly follows the first stagecoach route through the Black Canyon, established in 1878 between Cañon (now Black Canyon City) and Prescott. A later highway through White Spar from Wickenburg to Yarnell was improved in 1925 and incorporated into US 89 in 1926.{{cite news |last=Corbett |first=Peter |date=September 21, 2018 |title=How the I-17 Black Canyon Freeway evolved from stage route to modern highway |url=https://azdot.gov/adot-blog/how-i-17-black-canyon-freeway-evolved-stage-route-modern-highway |work=ADOT Blog |publisher=Arizona Department of Transportation |accessdate=November 6, 2022}}

In 1936, SR 69 was established as a state route from Phoenix north to Prescott.{{cite map|publisher=Rand McNally|title=Arizona and New Mexico Road Map|year=1938|url=http://www.arizonaroads.com/maps/index.html|access-date=November 27, 2011}}{{cite web|url=http://www.azhighwaydata.com/resolutions/?syear=&submit1=Submit&eyear=&crc=3&rtnum=69&page=4|author=Arizona Department of Transportation|author-link=Arizona Department of Transportation|access-date=April 22, 2008|title=ADOT Right-of-Way Resolution 1936-P-624}} The road was completed by 1940 to Prescott. In 1954, a new route north to Flagstaff was established as SR 79. In May 1956, the Black Canyon Highway from Phoenix to Flagstaff was completed, but not to Interstate standards.{{cite map |publisher=Rand McNally |title=State Highway Department Road Map of Arizona |year=1961 |url=http://www.arizonaroads.com/maps/index.html |access-date=November 27, 2011}} It was incorporated into the new Interstate Highway System, established by the federal government later that year, and designated as part of I-17.

The first interchange on the Black Canyon Freeway was built in 1950 west of downtown Phoenix and was extended to Grand Avenue in 1957.{{cite news |last=Nothaft |first=Mark |date=February 21, 2017 |title=Which freeway came first in the Valley? |url=https://www.azcentral.com/story/news/local/phoenix-contributor/2017/02/21/which-freeway-came-first-valley/97871258/ |work=The Arizona Republic |accessdate=November 6, 2022}} The freeway was extended to McDowell Road by 1971 and out of the Phoenix suburbs by 1974, at a cost of $33 million. By 1971, I-17 had been completed from Phoenix northward to Camp Verde where a short stretch had not been completed to standards. The stretch from SR 279 (now SR 260) north to SR 179 was also complete. The largest section yet to be completed was from SR 179 north to Flagstaff. This segment was still just a two-lane roadway, but it did have full traffic interchanges built at crossroads. The portion from I-40 south to the Flagstaff Municipal Airport had been completed by this time.{{cite map |publisher=Arizona State Highway Department |title=State Highway Department Road Map of Arizona |year=1971 |url=http://www.arizonaroads.com/maps/index.html |access-date=November 27, 2011}} The final section of I-17, near Camp Verde and Montezuma Castle, began construction in February 1977 and opened to traffic in August 1978.{{cite news |date=May 18, 1978 |title=Last Link of I-17 To Open in August |page=15 |work=The Arizona Republic |url=https://www.newspapers.com/clip/112675527/last-link-of-i-17-to-open-in-august/ |via=Newspapers.com |accessdate=November 6, 2022}}

In 1993, officials in Arizona proposed an extension of I-17 to connect with I-15 in Utah.{{cite news|url=https://www.deseret.com/1993/1/2/19024583/arizona-officials-seek-extension-of-i-17-into-utah|title=Arizona officials seek extension of I-17 into Utah|date=January 2, 1993|agency=Associated Press|publisher=Deseret News|access-date=January 27, 2021}}{{Clarify|date=February 2021}}

The existing interchange with Happy Valley Road in Phoenix was converted to a diverging diamond interchange (DDI). The project was finished in the fall of 2020.{{Cite web|url=https://www.azdot.gov/projects/central-district-projects/i-17-ti-reconstruction-happy-valley-rd-and-pinnacle-peak-rd/happy-valley-rd|title=Happy Valley Road|website=www.azdot.gov|access-date=2019-08-26}}

Due to increasing weekend traffic on I-17 between the Phoenix area and northern Arizona, primarily between Phoenix in the south, and Sedona, Flagstaff, and the Grand Canyon in the north, ADOT started plans to widen a {{convert|34|mi|km|adj=on}} section of four-lane freeway between Anthem and the Sunset Point Rest Area in 2018.{{Cite web |title=Connecting Arizona - Improving I-17 |publisher = Arizona Department of Transportation |url=https://www.improvingi17.com/}} In 2021, the design was chosen, with a standard third general-purpose lane set to be added in both directions between Anthem and Black Canyon City, but due to the mountainous topography north of Black Canyon City to Sunset Point, two flex lanes will be added in a separate carriageway next to the existing southbound lanes. The lanes will be allocated depending on whichever direction has the most traffic, generally this will be northbound traffic from Monday through Saturday, and southbound traffic on Sundays. A combination of six different safety systems (vehicle arresting barriers, automated arm gates, concrete barriers, steel gates, dynamic messaging signs, and cameras) will control access to these lanes.{{Cite web |title=Connecting Arizona - Improving I-17 - Flex Lanes |publisher = Arizona Department of Transportation I-17 Improvements |url=https://www.improvingi17.com/flex-lanes/}} Construction began in 2022 and in May 2025, the additional lanes from Anthem to Black Canyon City opened.{{Cite web |last=Bontke |first=Jordan |title=Third lane on I-17 north of Phoenix opens ahead of Memorial Day weekend |website=ABC 15 Arizona |url=https://www.abc15.com/news/operation-safe-roads/i-17-opens-third-lane-ahead-of-memorial-day-weekend |date=May 22, 2025}}{{Cite press release |title=New I-17 lanes open between Anthem and Black Canyon City |publisher=Arizona Department of Transportation |url=https://azdot.gov/news/new-i-17-lanes-open-between-anthem-and-black-canyon-city |date=May 22, 2025}} The flex lanes are scheduled to be completed by the end of 2025.

Due to increasing weekend traffic on I-17 between the Phoenix area and northern Arizona, ADOT plans to widen a section of freeway between Black Canyon City and the Sunset Point Rest Area. The current span is only four lanes wide and is subject to frequent traffic jams on weekends as motorists travel to and from Sedona, Flagstaff, or other high country destinations. Two flex lanes will be added in a separate carriageway next to the existing southbound lanes. The lanes will be allocated depending on whichever direction has the most traffic, generally this will be northbound traffic from Monday through Saturday, and southbound traffic on Sundays. A combination of six different safety systems (Vehicle Arresting Barriers, Automated Arm Gates, Concrete Barriers, Steel Gates, Dynamic Messaging Signs, and Cameras) will to control access to these lanes.{{cite web|url=https://azdot.gov/planning/transportation-studies/i-17-anthem-way-sunset-point/recommended-build-alternative-i-17| title=Recommended Build Alternative - I-17: Anthem Way to Sunset Point| accessdate=August 26, 2021| publisher = Arizona Department of Transportation }} Construction began in 2022 and is scheduled to be completed by the end of 2025.{{cite news |title=First girders installed on Interstate 17 improvement project |url=https://ktar.com/story/5480074/first-girders-installed-on-interstate-17-improvement-project/ |access-date=April 27, 2023 |work=KTAR.com |date=April 4, 2023 |language=en}}

I-17 has the unusual distinction of starting at approximately milepost 194 instead of at milepost 0.{{cite map |author=Multimodal Planning Division |date=January 2014 |title=Phoenix Area Milepost System |url=https://apps.azdot.gov/files/CNS/F014701C/F014701C_Phoenix_Area_Milepost.pdf |publisher=Arizona Department of Transportation |accessdate=November 6, 2022}} This is a holdover from Arizona's old system of marking mileposts, where a branching route would continue the milepost numbering of its original host, instead of starting over at zero.{{cite web |first = Caroline |last = Carpenter |title = Marking the Miles One Milepost at a Time |date = June 13, 2017 |url= https://azdot.gov/blog-article/marking-miles-one-milepost-time |work = ADOT Blog |publisher = Arizona Department of Transportation |access-date = January 30, 2025 }} I-17 inherited its milepost locations from SR 69, which the freeway replaced between Phoenix and Cordes Junction.{{cite news |last=LaBarbera |first=John |date=May 19, 2022 |title=Throwback Thursday: Future I-17 |url=https://azdot.gov/adot-blog/throwback-thursday-future-i-17 |work=ADOT Blog |publisher=Arizona Department of Transportation |accessdate=November 6, 2022}} SR 69's mileposting was such that it coincided with US 89's mileposting, which was 201.6 where the two routes intersected. When I-17 was constructed, the existing mileposting for SR 69 was retained.

State Business Route 17 (also known as SR 17 Bus.) was a former {{convert|3|mi|km|adj=on|spell=in}} business loop of I-17 that served the west side of Black Canyon City, Arizona. SR 17 Bus. followed Old Black Canyon Highway (formerly SR 69 before I-17 replaced most of the route between Phoenix and Cordes Junction) from exit 242 south of town at a diamond interchange to another diamond interchange at exit 244 north of town. The business route was subsequently transferred from state to local maintenance and because of ADOT's policy of not signing business loops on nonstate maintained roadways, the route was decommissioned in 2011.{{cn|date=November 2024}}
