Project Description
The new road features two 12-foot lanes in each direction with a 44-foot grassed median and 16-foot shoulders within a 200-foot right-of-way. The speed limit is 45-mph through the first two curves east of SR 20 and then 55-mph for the remaining length of the project. The route includes upgraded, signalized intersections at State Route 20, New Hope Road, Martins Chapel Road, Campbell Road, and a half-cloverleaf interchange at State Route 316.
The Extension crosses over Chandler Road and under Hiram Davis Road and Alcovy Roads. Bramlett Shoals Road on either side of the extension is closed and now consists of a new, two-lane connector road constructed from Hiram Davis Road to Bramlett Shoals Road.
