I-85 Widening and Improvements in Cabarrus County


The North Carolina Department of Transportation is constructing four additional general-purpose travel lanes (two in each direction) to approximately eight miles of I-85 from north of N.C. 73 (Exit 55) to north of Lane Street (Exit 63) in Cabarrus County. Interchange improvements are also planned for interchanges at U.S. 29/601 (Exit 58), Dale Earnhardt Boulevard (Exit 60) and Lane Street (Exit 63).

This project will complete the expansion of I-85 through the county, providing a greater level of service for local and through traffic.

Project Overview and Purpose

The primary purpose of this project is to improve traffic flow on I-85 and the interchanges in the project area.

Without these improvements, traffic volumes are predicted to increase each year and exceed capacity by 2035. Some of the major elements of the project include:

  • Converting the existing interchange at U.S. 29/601 to a diverging diamond interchange (DDI)
  • Improving the I-85 interchange with Dale Earnhardt Boulevard by widening the road, modifying existing loops and building new loops, and providing additional full-access intersections in the area
  • Replacing the Lake Fisher bridge on Brantley Road in Kannapolis
  • Realigning Winecoff School Road in Kannapolis and eliminating the existing at-grade crossing
  • Replacing/rebuilding several structures over I-85 to meet today’s design requirements and eliminate substandard clearances

Resources for Local Property Owners

In many cases, it is inevitable that a certain amount of private property must be acquired. The displacement of homes and businesses is minimized to the extent practicable. The following brochures will answer questions about this process.
