Interstate 24 Tennessee

Interstate 24 Tennessee
In the state of Tennessee, Interstate 24 runs from Clarksville to Chattanooga by way of Nashville. Just west of Chattanooga, I-24 drops into Georgia for 4 miles (6 km).

One of the most notoriously hazardous stretches of Interstate highway in the United States is approximately 40 miles (64 km) west of Chattanooga on I-24 in Monteagle, where the highway goes over the Cumberland Plateau. Compared to grades elsewhere, Monteagle's 4 to 6% grade does not come close to the steepest highway roads (the Siskiyou Pass of Interstate 5 in Oregon has some the steepest grades in the nation), but the slope is protracted over a distance of several miles.

Interstate 124 is an occasional (currently unsigned) designation of a portion of the US 27 freeway which runs as a spur into downtown Chattanooga and beyond. Also in Chattanooga is the "Ridge Cut", a 1/4 mile section of Missionary Ridge, between the 4th Avenue exit and the Germantown/Belvoir exit. Accidents and severe congestion are common here.
