Interstate 124 overlays U.S. 27 north from the Big Scramble Interchange with I-24 to Downtown Chattanooga and the P.R. Olgiati Bridge spanning the Tennessee River. The 1.95 mile long route is unmarked, with signs only referencing the freeway as U.S. 27. A remaining sign for I-124 was posted at the 4th Street end of the Olgiati Bridge until at least 1998. Most of the I-124 signs were replaced with U.S. 27 several years before due to confusion among non-local motorists with identifying I-24 versus I-124.1

Underway from December 2015 to Fall 2020, a $142.9 million project reconstructed 2.29 miles of U.S. 27, including the entire length of Interstate 124. The freeway was originally built in the 1950s and early 1960s. Work straightened out an S-curve, expanded the capacity to six overall lanes plus auxiliary lanes, modified interchanges at W Main Street, MLK Boulevard and E 4th Street, and replaced several bridges. The Ogliati Bridge was also widened with an additional lane per direction and outside shoulders.

U.S. 27 extends northward along a freeway from Chattanooga to Red Bank, Soddy Daisy and SR 111. SR 111 continues the freeway west to U.S. 127 at Dunlap. This section was never apart of Interstate 124.
