The North Carolina Department of Transportation (NCDOT) has begun the planning and engineering studies to convert the existing grade separation of Old Holly Springs-Apex Road (SR 1153) and Triangle Expressway/Toll N.C. 540 to an interchange. The project would also construct auxiliary lanes along the Triangle Expressway between U.S. 1 and the N.C. 55 Bypass, a distance of approximately 2.0 miles. The central purpose of the Access 540 project is to improve access and roadway connectivity in response to planned and anticipated development in southern Apex.

Project Overview and Purpose
|Finding of No Significant Impact
|Open to traffic
|* dates subject to change
Traffic along Old Holly Springs-Apex Road is projected to increase by over 2,100 percent – from 1,900 Average Annual Daily Traffic (AADT) in 2010 to 43,000 AADT in 2035. The increase in traffic is due to planned and anticipated development in southern Apex. Currently, motorists desiring to access the Triangle Expressway from Old Holly Springs-Apex Road must follow a 4.5 to 5.5-mile path depending on the route chosen. The proposed interchange project would provide a direct local north-south connection between Old Holly Springs-Apex Road and the Triangle Expressway.
The proposed auxiliary lanes along Triangle Expressway would improve traffic flow and reduce vehicle conflicts. This includes providing an additional lane for entering and exiting traffic that is separate from the through lane.
The project is estimated to cost $19.6 million. Final costs will be determined during final design.
