Interstate 24

Routing

Interstate 24 takes a northwest-southeast orientation through Southern Illinois, Kentucky and Tennessee. The freeway even enters Georgia briefly. Facilitating traffic through Chattanooga, Nashville and Paducah, I-24 also provides a part of a route to more distant destinations such as Atlanta, Chicago and St. Louis. Some signage in Nashville even listed the western control city for Interstate 24 as St. Louis, even though the freeway does not go that far west.

Parallel/Historical U.S. Routes

Leading south from I-57 to Metropolis in Illinois, I-24 somewhat parallels U.S. 45. U.S. 45 leaves the freeway corridor at Paducah, Kentucky, with U.S. 60 paralleling the route east to Reidland and U.S. 62 through to I-69 at Eddyville. Angling southeast toward Clarksville, I-24 travels solo until the Hopkinsville vicinity, where U.S. 41 Alternate accompanies the route south into Nashville. U.S. 41 and I-24 parallel one another closely from the capital city of Tennessee south to Chattanooga. U.S. 64 and 72 join U.S. 41 as I-24 dips into Georgia as well.

History

The final portion of Interstate 24 in Illinois to open was the 14-mile highway between U.S. 45 north of Vienna to Interstate 57. This stretch opened in late January 1976 at a cost of $32.5-million.7

First conceptualized through western Kentucky in 1958, Interstate 24 was completed in Kentucky on May 23, 1980 when a 23-mile section opened to traffic from Western Kentucky Parkway to U.S. 68 east of Cadiz. Groundbreaking on the first portion of I-24 in the Bluegrass State took place in Lyon County in December 1967.1 The 28-mile section between U.S. 68 and the Tennessee state line opened in early September 12, 1975 at a cost of $29.7-million.2

The Ohio River bridge between Metropolis, Illinois and Paducah, Kentucky opened to traffic in October 1974 at a cost of $18.6 million.3 Structural problems discovered, including 119 cracks as a result of defective welding in the tie girders, led to the closure of the span on August 3, 1979.4,5 The tied-arch bridge remained closed to all traffic through October 1980 and truck traffic until summer of 1981.6

Within Nashville, Interstate 24 shares a short overlap with Interstate 65 leading south toward Downtown. Renumbering of Interstate 265 to I-65 in 2000 shortened the overlap between the two routes in an effort to better partition through traffic around Downtown.

Further south at Monteagle, Tennessee, the roadways of Interstate 24 separate by a substantial distance due to the terrain. I-24 was constructed across Monteagle Mountain between 1962 and 1968.8 The freeway incorporated a former three-lane route of U.S. 41 & 64 as the eastbound lanes of I-24. Reconstruction of the eastbound lanes to modern standards during the 1980s left the westbound lanes with two lanes of traffic per direction separated by a concrete barrier.9 The Ridge cut section of Interstate 24 in Chattanooga was dedicated on December 1, 1965.10
