The Tennessee Department of Transportation will be beginning a rockfall mitigation project near the area known as Petty Bluff on Dixon Springs Hwy (Highway 25) north of the Hwy 80 and Hwy 25 intersection by the end of the month.
From Monday, January 11, through Monday, January 18, traffic control measures will be installed. Traffic will be limited to one lane at a time with temporary automated signals on each end of the closure each day from 9:00am until 2:45pm. The roadway will be reduced to one lane those hours for the duration of the project. The current estimated completion date is September 30, 2021.
The project’s scope is scaling and trim blasting of the existing rock face to remove loose rocks, impediments, and vegetation/trees where root growth could cause rocks to dislodge in the future. A wire mesh rockfall drape will be installed along the rock’s face after completing the scaling and trim blasting.
Please see below for the approximate location of the lane closure based upon the provided TDOT information.
