PT Engineering (as a subconsultant to Dewberry Engineering, Inc.) developed a traffic capacity analysis for R‐2814D; widen US 401 (Louisburg Rd) to a four‐lane divided facility from SR 1103 (Flat Rock Church Road/Clifton Pond Road) to SR 1700 (Fox Park Road) in Franklin County. The study included the analysis of the 2017 and 2040 No‐Build Scenarios and 2040 Build scenarios. The analysis utilizes Synchro/SimTraffic for both signalized and unsignalized intersections. A superstreet configuration was analyzed and recommended for US 401 to maintain uniformity in cross sections and access control strategy.
