Ahhh Monteagle... Where you see the semi's parked at the Walmart in Jasper with the brakes smoking... Engines overheat going up, brakes overheat coming down. And the runaway truck ramps are on the left side of the road! But a beautiful section of highway. You can easily find that stretch of I-24 on any map. The lanes are widely seperated. Northbound lane is on one side of the mountain and the Southbound lane is on the other side. And no good way around it unless you take TN 111 and then switch to 128 at Dunlap. TN 111 (Corridor J) into the north side of Chattanooga has a steep grade as well but I rarely seen evidence that anyone took the runaway truck ramp. I drove Corridor J often as I used it to go to Chatt about once a week for many years. My bank was in Hixson. I used to live in Whitwell.
From Wiki https://en.wikipedia.org/wiki/Inters...ee_and_Georgia
One of the more hazardous stretches of Interstate highway in the United States[citation needed
] is located approximately 40 miles (64 km) west of Chattanooga on I-24 in Monteagle
, where the highway crosses the Cumberland Plateau
. Compared to grades elsewhere, Monteagle's 4–6% grade does not come close to the steepest (Interstate 40
between Nashville and Knoxville
features 5% grades in each direction as well as a 5% grade north of Nashville on 24, near Joelton
), 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
] As runaway trucks had been a regular and deadly occurrence, in part of the failure or inability of truckers to slow down to the 35 mph (56 km/h) truck speed limit once on the slope, the eastbound lanes were rebuilt in the late 1980s. This work reduced the grade, widened the road, added a required stopping area with traffic lights for trucks prior to descending the mountain, and added two 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. Owing to geography, these two ramps are on the left side of the grade. This stretch of highway inspired Johnny Cash
to write a song about Monteagle Mountain
... 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 sharp 45 mph (72 km/h) curve to the right while descending steeply at the same time. This downhill curve also features off-ramp approach style lane dividers, in order to slow both motorists and truckers. 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.
The Ridge Cut south of Moccasin Bend is a PITA due to traffic. Adding to the mess is the fact that the I-24/I-75 split is just south of the Ridge Cut and far too many peple try to cross multiple lanes of traffic at the last minute because they want to go South on I-75 into GA rather than Northeast on I-75 towards Knoxville.
