Interstate 124 (I-124) is an unsigned designation for a short segment of a four-lane limited-access highway located in Chattanooga, Tennessee. During periods where this two-mile-long (3.2 km) segment of U.S. Route 27 (US 27) has been signed as I-124, it has served as a spur route of I-24 to downtown Chattanooga. The road segment has not been signed as I-124 for several years[when?] (it is marked on overhead signs and mile markers as US 27), and the Tennessee Department of Transportation official map no longer designates it as I-124, but some DOT publications still make reference to the designation.[2]

Route description[edit]

The US 27 freeway diverges from I-24 just before the Moccasin Bend in the Tennessee River, continues north through downtown Chattanooga, and then across the Tennessee River as a limited-access freeway on the P. R. Olgiati Bridge. The river is the point at which the I-124 designation ended. After crossing the river, the freeway continues under the US 27 designation for another 30 miles (48 km) (beyond which the spur continues under the Tennessee State Route 111 designation for a further 20 miles (32 km)).
