PDF of TDOT’s proposed redesign of the intersection of Highway 46 and Pomona Road.
Because there is a significant amount of heavy traffic bound to and from the William D. Field-Dickson County Industrial Park using Pomona Road, the Tennessee Department of Transportation’s proposed improvements to Highway 46 include modifications to the intersection and its traffic signals. The $8.3 million Traffic System Management proposal says the geometrics of the Pomona Road intersection are inadequate for the amount of heavy traffic it sees. The proposal calls for improving the right-turn radius from the northbound lanes of Pomona Road by acquiring additional right of way from the new TriStar Bank branch. It recommends that the southeast quadrant of the intersection be redesigned and constructed to widen the existing channelized turn lanes on Highway 46 northbound. The study also recommends that the channelized right turns controlled by a yield sign for both Pomona Road approaches be removed. The traffic signals would be modified to control left and right turns for all four approaches to the intersection. While the plan says interconnection and coordination of traffic signals is critical to improving traffic flow, the signals at Pomona Road would remain independent. TDOT’s plan calls for a northern network of coordinated signals from Henslee Drive to Jackson Brothers Way and a southern network from Interstate 40 to Livestock Road, the Pomona Road intersection would not be a part of either network unless additional traffic signals are added on Highway 46. TDOT has begun survey work to prepare for the design phase of the Highway 46 improvement plan with a projected completion by 2017.
