Interstate 124 is the hidden designation for the Dayton Freeway (U.S. 27) leading north 1.97 miles to the P.R. Olgiati Bridge spanning the Tennessee River. I-124 was fully signed until the 1990s, when a TDOT project resigned the route to reference just U.S. 27 due to motorist confusion at the exchange with I-24.

06/12/17

I-24 east expands to four lanes ahead of the separation with Exit 178. The distributor roadway serves U.S. 27 [I-124] north to Downtown and Hill City in addition to the "Big Scramble Interchange" with U.S. 11-41-64-72 (Broad Street) and SR 58 (Market Street) in Southside, Chattanooga.

06/12/17

Exit 178 separates from the I-24 mainline with two lanes for U.S. 27 [Interstate 124] north and the ramps to Broad (U.S. 11-41-64-72) and Williams Streets.

The connection to I-124/U.S. 27 was separated as new Exit 178 B while Exit 178 A combines with an exit from I-124/U.S. 27 south to Broad Street. Broad Street leads U.S. 11-41-64-72 north from Alton Park near Lookout Mountain to Southside in Chattanooga.

U.S. 72 ends at the U.S. 41 turn onto Main Street. U.S. 11/64 turn east onto 20th Street to the immediate north.

U.S. 27 south combines with Interstate 24 east through the Big Scramble Interchange. The service road linking I-24 east with Broad and Market Streets forms an entrance ramp ahead of Exit 180 A for Central Avenue north.

06/12/17

Exit 180 A loops away from I-24 east to form Central Avenue north at adjacent U.S. 11/64 (23rd Street). Central Avenue continues to Chattanooga National Cemetery while Rossville Boulevard (SR 27) branches southeast from U.S. 11/64 to become U.S. 27 through East Lake / Clifton Hills.

While I-24 traverses Missionary Ridge along a elevated route and viaduct, U.S. 41/76 crosses the hill via the Bachman Tunnels. Built in 1929, the Bachman Tunnels comprise a pair of one-lane tubes with a low clearance.

06/12/17

01/21/13

Segment of 1 of the Phase 2 of I-75/I-24 Split project switched the location for the entrance ramp from Germantown Road and exit ramp for Moore Road north to Brainard. Work underway from Spring 2023 to 2025 also expands Interstate 24 east to the exchange (Exit 185) with I-75.¹
