In the U.S. 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 (Interstate 40 between Nashville and Knoxville features 5% grades in each direction), but the slope is protracted over a distance of several miles. While all motorists need to exercise caution, truckers are particularly vexed by Monteagle, and many have died going through this area.[citation needed] The east bound lanes feature several runaway truck ramps where a truck whose brakes have failed due to overheating can exit into a long pit full of loose gravel to safely stop. This dangerous stretch of highway inspired Johnny Cash to write a song about Monteagle Mountain.

Another interesting tidbit about the Monteagle grade is that it sports one of the 3 widest medians of any Interstate highway. (The other 2 being I-8 through the In-Ko-Pah grade in California and I-84 through the Cabbage Hill grade east of Pendleton, Oregon.) There is more than a mile between the eastbound and westbound lanes at one point. The eastbound lanes descend the mountain on one side of a ridge, while the westbound lanes ascend on the other side of the ridge. Also of interest on Monteagle Mountain is the steep grade on I-24 north of Monteagle. This steep grade occurs for Westbound traffic and features a very sharp 45 MPH curve to the right while descending steeply at the same time. This downhill curve also features off-ramp approach style lane dividers, too, in order to tell motorists and truckers both to slow down.

Interstate 124 is an occasional (currently unsigned but still occasionally mentioned in DOT publications) designation of a portion of the US 27 freeway which runs as a spur into downtown Chattanooga and beyond.[1] 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.
