Knoxville, TN road map

All three of mainline interchanges of Interstate 275 underwent reconstruction between December 1, 2006 and January 26, 2008 in anticipation of the "Smartfix" Interstate 40 project.1 The $20-million project reconfigured the compact full-cloverleaf interchanges (Baxter, Oldham and Heiskell Avenues) to eliminate weaving traffic movements and accommodate a 2.1-mile widening of the freeway from four to six lanes. Exits 1A/B became Exit 1A, Exits 1C/D became Exit 1B, and Exits 2A/B became Exit 2, all standard diamond interchanges. The work included an expansion of one mile of Interstate 640 as well.2

Interstate 275 was constructed in 1958 and signed as a part of the Interstate 75 mainline through Knoxville. A shift of the designation occurred in 1982, when Interstate 75 moved to the completed Knoxville bypass (Interstate 640) in time for the World's Fair.1 During that time frame, the freeway was reconfigured at the southern terminus with Interstate 40 and Oak Avenue. The cloverleaf interchange at I-40 was replaced with a high-speed stack interchange and the freeway end at Oak Avenue was replaced with ramps feeding into U.S. 441 (Henley Street).

U.S. 441 North
U.S. 441 brings traffic northward from Sevierville into the city of Knoxville to the Interstate 275 connector west of downtown. 08/23/03
The 2.98-mile freeway begins at a wye interchange with U.S. 441 (Henley Street) north ahead of Western Avenue (SR 62) and Summit Hill Drive. 08/23/03
Interstate 275 North
Interstate 275 commences and travels high above Interstate 40 from Henley Street to the eastbound off-ramp for Asheville, North Carolina. A multi level nterchange joins the two freeways adjacent to several Norfolk Southern Railroad tracks. 08/23/03
Downtown area traffic partitions between the Interstate 40 westbound loop ramp and the Interstate 275 northbound mainline. Traffic from Interstate 40 has yet to merge onto Interstate 275. Therefore only one lane of traffic continue northward at this point. 08/23/03

Interstate 275 passes over Bernard Avenue on quarter-mile approach to Baxter Avenue (Exit 1A). Originally a parclo interchange joined the freeway with West 5th Avenue to University Avenue. That connection was removed when the original cloverleaf with Interstate 40 was reconfigured in 1981/82. 08/23/03, 10/15/11
Three mainline exits of Interstate 275 originally consisted of compact cloverleaf interchanges. Pictured here was the Exit 1A ramp departure for Baxter Avenue eastbound and four-lane freeway mainline. Baxter Avenue travels nine blocks to its end at Folsom Street to the northeast. 08/23/03
The cloverleaf at Exit 1A was converted into a diamond interchange during 2006-07 as part of an overall project to widen Interstate 275 to six lanes. 10/15/11
Historical look at Interstate 275 northbound at the former Exit 1B cloverleaf ramp to Baxter Avenue westbound. One block to the west Baxter Avenue yields the westbound beginning of Beaumont Avenue. Beaumont Avenue links Baxter and Interstate 275 with Western Avenue (SR 62) an important east-west arterial between Knoxville and Oak Ridge. 08/23/03
A short distance to the north of the Baxter Avenue / Exit 1A is the former Exit 1C/D cloverleaf (now Exit 1B); this interchange was converted into a diamond interchange between 2006-07. 10/15/11

A fourth northbound lane travels Interstate 275 between Baxter Avenue and Exit 1B. Intersecting the freeway here is the east-west Oldham and Woodland Avenues. The naming convention of the surface street changes from Oldham to Woodland as one travels east under Interstate 275. 08/23/03, 10/15/11
Former Exit 1D departed for Oldham Avenue westbound. Woodland / Oldham Avenue represent one of four Norfolk-Southern Railroad crossings between Interstate 40 and Atlantic Avenue. The railroad corridor parallels Interstate 275 in a north-south fashion between I-40 and I-75-640. 08/23/03
A two-mile sign bridge for the exchange with I-75/640 and U.S. 25W appears at the former Exit 1D off-ramp location. 10/15/11
The third and final mainline exit is a diamond interchange between Interstate 275 and Heiskell Avenue. 10/15/11

Heiskell Avenue connects the freeway with Texas Avenue to the west and Central Avenue to the east. The Exit 2 ramp serves the Arlington and Lincoln Park neighborhoods of the city. 08/23/03, 10/15/11
Interstate 275 travels underneath Heiskell Avenue at the former Exit 2B loop ramp onto westbound. Heiskell Avenue in conjunction with Texas Avenue connects Interstate 275 with Western Avenue through northwest Knoxville. Formerly displayed here were guide signs for Exit 2B and the one half mile guide sign for Exit 3. Note that the Exit 3 panel ignored Interstate 75 in favor of just I-640/U.S. 25W. The sign likely dated from before Interstate 75 was relocated onto the Knoxville loop. 08/23/03
A new sign bridge was installed to replace overheads attache to the Heiskell Avenue overpass. U.S. 25W is only referenced for the exit from the westbound ramp to Interstate 640 & I-75 south. U.S. 25W runs alongside I-640 eastward to I-40. 10/15/11

Continuing northward on the final stretch of Interstate 275, the Heiskell Avenue on-ramp becomes an auxiliary lane for the Knoxville Bypass and U.S. 25W (Clinton Highway). Older signs ignored the fact that Interstate 75 southbound follows Interstate 640 west until at least 2003. 08/23/03, 10/15/11

Traffic destined for Interstate 640 east & U.S. 25W southbound depart Interstate 275 south at the Exit 3 loop ramp. I-640/U.S. 25W overlap for seven miles to Interstate 40 in east Knoxville. 11/08/09
