A project to expand the Sam Rayburn Tollway will be completed in December, according to a progress report the North Texas Tollway Authority issued this summer.
The project will add an additional lane in both directions from Denton Tap Road in Coppell to U.S. 75 in McKinney.
NTTA spokesman Michael Rey told Community Impact Newspaper, which first reported the progress in September, that the tollway widening is on schedule and on budget.
The NTTA report also says the project includes improving ramps at Preston Road in Plano to separate traffic for drivers exiting the Sam Rayburn Tollway and entering the Dallas North Tollway.
Rey told Community Impact that traffic congestion on the Sam Rayburn Tollway led to the construction of a fourth lane.
“It was obvious to anybody who has traveled the [tollway] in the past few years ... traffic was certainly ramping up,” he told the newspaper.
Funding for the $200 million project comes from NTTA’s Capital Improvement Fund, the newspaper reported, and is not expected to raise toll rates.
