PDF of overview of TDOT’s proposal for the southern section of the Highway 46 improvement plan from Pomona Road to Interstate 40.
While the Tennessee Department of Transportation’s plan for improving Highway 46 includes the addition of four new signalized intersections, the Traffic System Management proposal also allows for the possibility of additional traffic signals as development continues along Dickson County’s busiest road. Although it is not listed as one of the new locations for traffic signals, the study acknowledges the likelihood that another traffic signal will be installed at The Crossings of Dickson, a planned retail development between Highway 46 and Beasley Drive referred to in the plan as the Thornton Development. The city and county have already approved a tax incentive program to assist the developers in the construction of a new road for the shopping center that includes the installation of traffic signals on Highway 46 and Beasley Drive. But that installation is not included in the $8.3 million traffic improvement plan because the cost will be borne by the developers. Mayor Don Weiss said TDOT planners are aware of the development proposal and the traffic signal will be coordinated with other signals in the north section of the plan. The study also mentions the possibility that continued development could warrant other traffic signals at the proposed site of the Dickson County Family YMCA and at Crestview Park. “Analysis indicate that when the Thornton Development, YMCA Development and the Crestview Development and their associated site plans reach full build out, the intersections created by these developments will warrant traffic signals,” the plan states. No costs for those potential signal needs are included in the $5.5 million state share and $2.8 million city share of the TDOT proposal. “All development in the area should be monitored to determine if traffic signals will be warranted,” the study concludes. With those three potential sites for new traffic signals, the changes to improve traffic flow on Highway 46 could end up with 15 signalized intersections in the five-mile stretch of highway from Interstate 40 to Henslee Drive, a stretch currently with only eight traffic lights.
