The proposed construction will widen US278/SR12 to provide two 12-ft. travel lanes in each direction separated by a 24-ft. raised grassed median with 10-ft. rural outside shoulders (6.5-ft. paved). The existing bridges over the Alcovy River and Overflow will be replaced with 88-ft. wide bridges with 24-ft. raised concrete medians in lieu of two sets of parallel bridges. The intersection of State Route 142 with State Route 12 will be reconstructed to be a round-a-bout in lieu of a traffic signal installation. The speed design for the project is 45 MPH from the Covington City limits M.P. 7.97 to M.P. 10.43 on State Route 12. The project limits are from the Covington City Limits M.P. 7.97 to just east of State Route 142 M.P. 10.43.
