State Route 112 (Clarksville Highway)

Overview

The proposed improvements for State Route 112 (Clarksville Highway) include widening the route from two lanes to four lanes with a continuous left turn lane, from the Ashland City Highway (SR 12) intersection to the Briley Parkway (SR 155) interchange. The project would also include intersection improvements at Clarksville Pike and Ashland City Highway, bridge replacement over White’s Creek, traffic signal upgrades at King’s Lane and West Hamilton Road (east) intersections, and the addition of bike lanes and sidewalks.

Upon completion of the widening of this section, the route will be a full five-lane facility, from the Martin Luther King Bridge over the Cumberland River to Briley Parkway, greatly improving the level of service.

Design

Ashland City Highway – Includes four 11’ travel lanes, dual 11’ left turn lanes, one auxiliary lane of varying width (0’ to 12’), two 4’ bike lanes and two 5’ sidewalks within 121’ of minimum Right of Way. The project begins approximately 800+ feet southeast of the Ashland City Highway intersection and transitions from 12’ lanes to 11’ lanes just north of the intersection.

Kroger/Fairview – Includes four 11’ travel lanes, one 12’ continuous left turn lane, two 4’ bike lanes and two 5’ sidewalks within 97’ of minimum Right of Way.

King’s Lane/Briley Parkway Interchange – Includes four 12’ travel lanes, one 12’ continuous left turn lane, two 4’ bike lanes, two 5.5’ grass strips and two 5’ sidewalks within 112’ of minimum Right of Way. The travel lane widths transition from 11’ back to 12’ just north of King’s Lane.
