The North Carolina Department of Transportation (NCDOT) is conducting the planning and engineering studies to convert the existing grade separation at the Triangle Expressway (Toll NC 540) and Old Holly Springs-Apex Road (SR 1153) to an interchange. The project would also construct auxiliary lanes along the Triangle Expressway between the N.C. 55 Bypass and US 1, a distance of approximately 1.5 miles. The purpose of the Access 540 project is to improve accessibility and north-south connectivity within southern Apex by providing a direct local link between the Triangle Expressway and Old Holly Springs-Apex Road.

Project Overview and Purpose
|Construction Bids Opened
|Open to Traffic
|* Note: Schedule is preliminary and subject to change
Traffic along Old Holly Springs-Apex Road is projected to increase substantially – from 1,900 Average Annual Daily Traffic (AADT) in 2010 to 34,900 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 the Triangle Expressway and Old Holly Springs-Apex Road.
The proposed auxiliary lanes along the 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 $31 million, which includes construction, utility modifications, environmental mitigation and right-of-way acquisition. Actual cost will be determined during final design.
