The 4-way intersection of HWY 70 at Miller Ave and Peavine in Crossville is currently an all-way stop and TDOT is now in the process of making it a roundabout. The construction work has begun and will result in lane closures on weekdays. This work is expected to be completed by 10/31/2023.
According to a TDOT safety study, roundabouts improve safety, promote lower speeds and traffic calming, reduce conflict points, lead to improved operational performance, and meet a wide range of traffic conditions because they are versatile in size, shape, and design.
During a 3-year study of this intersection (from 2018 to 2021), there were 14 reported crashes. Seven of these crashes were right-angle crashes. There were seven crashes with injuries.
TDOT is working on a single-lane roundabout that would keep the existing bypass right turn lanes on all four corners. Fortunately, the department already has enough right-of-way at the intersection to accommodate this design. This roundabout will include a 10’ mountable truck apron to allow large vehicles with trailers to negotiate the intersection.
At this time, the right-turning ramps have been closed in all directions to perform grading activities. Motorists should be aware of the changed traffic pattern and use caution while driving through the work zone.
