Project Overview

In order to address heavy directional traffic, proposed improvements include converting U.S. 17 /N.C. 172 intersection to a Continuous Green T-intersection configuration, implement access control measures along U.S. 17 by redirecting left turns at the U.S. 17/Old Folkstone Road intersection, and adding a new connector roadway between Old Folkstone Road and N.C. 172. 

At the Continuous Green T-intersection:

  • The southbound thru-movement on the main arterial (U.S. 17) does not stop.  As a result, stop and go delay associated with traffic signals for this southbound movement is eliminated and more green time can be devoted to the other movements. 
  • The other movements will continue to use the traffic signal as normal and function the same as a typical T-intersection. 
  • Left turns from the side street (N.C. 172) will turn into a channelized lane in order to merge with the main thru-movement. 

Project Highlights

Two Alternatives are being evaluated for the project.

Alternatives 1 and 2 both include the continuous Green T-intersection improvements at U.S. 17/N.C. 172.  All also include a connector roadway between Old Folkstone Road and N.C. 172. 

They differ in the location of the tie-ins to both existing roadways.  Alternatives 1 and 2 were shown to the public at the July 2019 Public Meeting.    

Benefits of a Continuous Green T-Intersection

  • Reduced Delay at Intersection: free flow thru-movement allows additional time to be allotted to minor movements and reduces overall delay.
  • Improved Safety: channelized left turns from side street reduce risk of angle crashes.
  • Reduced Travel Time: reduced delay along the main arterial by eliminating stop and go conditions and delay associated with traffic signals.

Resources for Property Owners

Although the N.C. Department of Transportation works to minimize the number of homes and businesses displaced by a road project, it is inevitable, in many cases, that a certain amount of private property is needed. The following information explains right of way acquisition and answers questions about the process.
