The N.C. Department of Transportation proposes to add additional lanes on Catawba Avenue from U.S. 21/ Statesville Road to Ferry Street, and along U.S. 21/ Statesville Road/ Holiday Lane to improve traffic operations at the existing U.S. 21 (Statesville Road) and Catawba Avenue intersection in Cornelius.

This project is included in the State Transportation Improvement Program (STIP) as Project Number C-5621.

Project Need:

The project area has experienced notable growth and development, leading to increased traffic volumes and congestion. Existing (2016) traffic volumes along Catawba Avenue and U.S. 21 (Statesville Road) in the project area are approximately 30,000 and 15,000 vehicles per day, respectively. Future (2040) traffic volumes along Catawba Avenue are projected to exceed 45,000 vehicles per day.

Project History:

The N.C. Department of Transportation evaluated four design options. These options included a roundabout, a quadrant intersection, a continuous flow intersection (CFI), and dual roundabouts. Based on a review of impacts associated with each option, and in coordination with the Town of Cornelius and neighborhoods adjacent to the project, the dual roundabout option was selected as the preferred alternative.
