Project Fortify

About the I-40/I-440 Rebuild

Long-term work is underway to rebuild an 11.5-mile stretch of I-40/I-440 in southern Raleigh that is in need of repair as the result of both crumbling asphalt and heavy traffic.

The Fortify I-40/I-440 Rebuild project – set to be complete in fall 2017 – is part of a 10-year plan to strengthen North Carolina’s roadways and alleviate traffic congestion in the Triangle.

The Fortify project includes these major improvements:

  • Replacing the pavement along the southern stretch of I-40/I-440
  • Extending the lanes between ramps in each direction at:
    • U.S. 1/64 (Exit 293)/Gorman Street (Exit 295)
    • Gorman Street (Exit 295)/Lake Wheeler Road (Exit 297)
  • Extending the deceleration (off-ramp) lane for Rock Quarry Road (Exit 300-B)
  • Rehabilitating 14 bridges within the project zone

Safety is the primary purpose of the project.

The 30-year-old pavement and materials underneath I-40/I-440 are cracking and crumbling from a chemical reaction triggered by a substance used in paving several decades ago. The damage is worsened by the more than 120,000 vehicles on the highway every day.

In an effort to minimize the effects of construction in the Fortify work zone, three lanes remain open in both directions for most of the I-40 rebuild portion of the project. NCDOT has also invested $12 million in public transportation options in an effort to reduce daily traffic in the area by 30,000 vehicles.

Phase I

May 2013 to Summer 2015:
Status: Complete

This part of the project extends 3.5 miles from the I-40/I-440/U.S. 64 interchange, at Exit 301, to just north of I-495/U.S. 264/Knightdale Bypass, at Exit 14.

Phase II

Late 2014 to Spring 2018:
Status: Under construction

This part of the project extends 8.5 miles on I-40 between U.S. 1/64 and the I-40/I-440/U.S. 64 interchange. All travel lanes to be open by late 2017; resurfacing and related work complete in 2018.

Help Us Fortify

About 120,000 vehicles travel daily through the work zone. Reducing that number by 30,000 could help improve traffic conditions during morning and afternoon commutes.
