The proposed project would consist of improvements to SR 12/US 278/Covington Highway @ 1-285. These improvements would include the construction of an additional right turn lane on the 1-285 northbound off-ramp and would increase the storage length to the 1-285 southbound off-ramp turn lanes. In addition, the radius of the right turn lane for the 1-285 northbound ramp would be increased. The proposed project would also include the construction of concrete islands at the 1-285 northbound off-ramp and the 1-285 southbound on-ramp. Crosswalks would be installed at the 1-285 northbound/southbound ramps and at Margarette Drive. Sidewalks would be constructed on the south side of Covington Highway west of the interchange and on both sides of Covington Highway east of the interchange. Curb and gutter would be replaced along Covington Highway. Also, an additional lane in the median on Covington Highway would be installed. The existing right-of-way along Covington Highway is 76 to 100 feet. The proposed right-of-way would range from 80 to 100 feet.
