I-40/I-440 Interchange & I-40 Widening

Project Overview

Planning and development are underway on two proposed projects to accommodate projected increases in traffic in Wake County over the next 25 years. Work would involve:

  • Adding lanes on I-40 from the I-440/U.S. 64 interchange to Lake Wheeler Road to improve the traffic-carrying capacity of I-40 (STIP I-5701)
  • Rebuilding the existing interchange at I-40/I-440/U.S. 1/U.S. 64 (STIP I-5703)

One of the nation’s fastest-growing counties, Wake County reached 1 million residents in 2014, and the population is expected to double by 2054.

This additional growth will increase traffic volumes by 55-70 percent on these roadways, which are important, high-volume corridors in North Carolina. I-40 and I-440 serve both commuter and long-distance traffic. U.S. 1 is also a primary local route as well as an important route for travel to Virginia and the mid-Atlantic region.

Project Funding

For funding purposes, this project is listed as two projects – I-5701 and I-5703 – in the N.C. Department of Transportation's State Transportation Improvement Program and is funded for a combined total of $179 million.
