This project will add four additional 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. This project will complete the interstate’s expansion through the county, providing a greater level of service for local and through traffic.

Interchange improvements are proposed at U.S. 29/601 (Exit 58), Dale Earnhardt Boulevard (Exit 60) and Lane Street (Exit 63). The existing at-grade rail crossing on Winecoff School Road in Kannapolis will also be eliminated.

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.

  • The level of service (LOS) is the measure of a roadway’s ability to carry traffic, with “A” being the highest, “F” being the lowest. If no improvements are made to this segment of I-85, traffic volumes will increase each year and exceed capacity by 2035. In fact, it is likely several segments of I-85 will operate at an “F” LOS during morning and/or afternoon peak times prior to 2035.
  • The proposed widening will improve the LOS on I-85, both for local and through traffic.

Another benefit will be the improvement to vertical clearance under the structures crossing I-85 to meet current design standards.

  • Many of the structures over I-85 were built in the 1960s and have substandard clearances. The project’s proposed improvements include replacing or rebuilding the structures to meet today’s design requirements.

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.
