Two additional travel lanes—one in each direction—are now open on the Sam Rayburn Tollway as part of the North Texas Tollway Authority’s expansion project.

The $200 million expansion of the 26-mile highway, which runs between US 75 in McKinney and Denton Tap Road in Coppell, took three years to complete, according to a news release. The project, which started in January 2019, widened the tollway to four lanes in each direction.

The tollway expansion’s goal was to improve regional mobility as North Texas’ population continues to grow and is projected to exceed 11 million people in the coming years.

“This expansion will help to decrease traffic congestion for our customers,” said Elizabeth Mow, NTTA assistant executive director of infrastructure. “The widened toll road will give drivers a safe, smooth and convenient travel option in a rapidly expanding travel corridor.”

Funding for the project came from the NTTA’s Capital Improvement Fund. According to NTTA officials, the widening project is not expected to contribute to increased toll rates.
