Interstate 275 (I-275) is an Interstate Highway in Tennessee that serves Knoxville by connecting the downtown with I-75/I-640/US Route 25W (US 25W). Measuring Script error: No such module "convert". in length,[1]Template:Efn it runs from a northern terminus at the junction with I-75/I-640/US 25W to a southern terminus at I-40. I-275 was formerly a section of I-75, which was rerouted onto I-640 in 1980 after a section of that route was completed.

I-275 begins at a complicated interchange with I-40 in Downtown Knoxville. US 441 southbound (Henley Street), State Route 62 (SR 62, Western Avenue), and 11th Street are also directly accessible from I-275 southbound at this interchange, and northbound I-275 is directly accessible from US 441 northbound and SR 62 here. About Script error: No such module "convert". north of this point, I-275 has an interchange with Baxter Avenue and then Woodland Avenue about Script error: No such module "convert". later. The route then curves sharply to the northwest and then sharply to the northeast about Script error: No such module "convert". later and crosses a railroad before reaching an interchange with Heiskell Avenue about Script error: No such module "convert". later. Passing through Sharp's Gap, a low point in Sharp's Ridge, I-275 reaches its northern terminus with I-75, I-640, and US 25W about Script error: No such module "convert". later. At this interchange, the route crosses I-640, and continues north as I-75. US 25W northbound is accessible from a flyover ramp that splits off from I-275 northbound about Script error: No such module "convert". south of I-640.[2]

History

The freeway that is now I-275 was first planned in the 1940s as part of a series of freeways for the city of Knoxville and was known initially as the North–South Expressway. The route was integrated into the Interstate System as part of I-75, and the southern terminus was the end of a concurrency with I-40 and I-75. Work on most of the route began in March 1958, and the first section, located between I-40 and Baxter Avenue, opened on October 28, 1960, after several delays.[3][4] The final section, located between Oldham Avenue and Heiskell Avenue, opened on January 24, 1962.[5][6] A dedication ceremony for this section took place on February 9, 1962.[7][8]

On December 6, 1979, TDOT submitted an application to the American Association of State Highway and Transportation Officials (AASHTO), requesting relocation of I-75 onto the then-underconstruction western leg of I-640 and renumbering of the route between I-40 and I-640/I-75 as I-275. The application cited the shorter distance and fewer number of interchanges that through traffic on I-75 would be required to traverse.[9] The change was also intended to divert through traffic away from traffic generated by the 1982 World's Fair.[10] AASHTO approved this redesignation on June 22, 1980.[11] Signs for I-275 were posted on December 17, 1980,[12] and the western leg of I-640 was opened to traffic six days later.[13][14]

Between December 1, 2006, and January 26, 2008, the existing cloverleaf exits (1A–B, 1C–D, 2A–B) were replaced with traditional diamond interchanges to add a continuous third lane in each direction. This was done to handle increased traffic flow for the shutdown of I-40 in Downtown Knoxville that took place on May 1, 2008.[15] I-275 was the designated detour route for I-75 northbound traffic during the I-40 shutdown to avoid traffic congestion at the I-75/I-640/I-275/US 25W junction as the ramp for I-75 northbound from I-640 eastbound is only one lane.[16]
