Interstate 24


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.

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

Western Terminus - Interstate 57 - Pulleys Mill, Illinois
Perspective from Interstate 24 west
Upon the departure of the first Illinois interchange on Interstate 24 westbound (Exit 37 with U.S. 45 at Metropolis), a mileage sign foretells of the pending junction with Interstate 55. Exit 16 with Illinois 146 at Vienna is 20 miles to the northwest, representing the next point of significance of Interstate 24. There is an interchange at Exit 27 between here and there. Photo taken by Chris Patriarca (07/18/03).
The final mainline interchange of Interstate 24 is Exit 7. This rural junction is situated within the Shawnee National Forest southeast of Illinois 37 at Goreville. This mileage sign confirms the distance to Interstate 57. Photo taken by Chris Patriarca (07/18/03).
Traveling to within two miles of the western terminus of Interstate 24. Featured in the background is an overpass of the Norfolk-Southern Railroad line. Beyond that crossing is the overpass of Illinois 37. The state route shadows Interstate 57 from Interstate 24 northward to the city of Effingham near the junction with Interstate 70. Photo taken by Chris Patriarca (07/18/03).
Interstate 24 ends one mile guide sign. The terminus interchange itself is located along the Johnson and Williamson County line. The closest city of significance is Marion, the Williamson County seat. This community is is nine miles to the north via Interstate 57. Photo taken by Chris Patriarca (07/18/03).
Exit 44A/B sign bridge on Interstate 24 westbound for Interstate 57. The numbering convention is not of Interstate 24, but instead of Interstate 57. This format is also used for Interstate termini in the city of Little Rock, Arkansas. Interstate 24 is often signed with Saint Louis as the control city. Since the route does not actually travel to the city, an auxiliary panel is displayed to advise motorists to Interstate 57 north (to Interstate 64 west). Photo taken by Chris Patriarca (07/18/03).
The Interstate 24 mainline defaults onto Interstate 57 northbound via Exit 44B ahead. Otherwise traffic wishing to turn southwest toward Anna, Mounds, and Sikeston will depart via Exit 44A to the right. Photo taken by Chris Patriarca (07/18/03).
An end shield is posted at the western terminus of Interstate 24. This rural junction is situated within the Shawnee National Forest, just west of Lake Egypt and the village of Pulleys Mill. Photo taken by Richie Kennedy (07/00).
The conclusion of Interstate 24 westbound. Interstate 57 southbound traffic will travel four miles to the next interchange (Exit 40). The road encountered is the same that Interstate 24 meets at its first interchange. In the background is the one mile guide sign for the next northbound interchange, that of Exit 45 with Illinois 148. Photo taken by Chris Patriarca (07/18/03).
A reminder for Saint Louis bound traffic interests along Interstate 57 after the merge from Interstate 24. Interstate 57 merges for five miles with Interstate 64 at the city of Mount Vernon. This overlap occurs between Exits 73 and 78. Photo taken by Chris Patriarca (07/18/03).

Western Kentucky - 1970 Kentucky Official Highway Map
Very little of Interstate 24 was under construction by 1970 in Kentucky. The National System of Interstate and Defense Highways plan in 1955 only included I-24 between Nashville and Chattanooga. The extension northwest to Illinois was included with the additions approved in October 1957.
Central Nashville, Tennessee - 1969
Interstate 24 ran northwest from La Vergne (Exit 62) to temporarily end on the overlapped section with Interstate 65 at Maplewood (Exit 44) by 1970.
