The North Texas Tollway Authority is adding an extra lane to ease traffic flow. If you drive Sam Rayburn Tollway regularly, you'll notice construction starting west of Denton Tap Road to the U.S. 75 ramp. The North Texas Tollway Authority is adding a fourth lane in the median in both directions to improve capacity.
For the most part, traffic won't be disrupted. However, three bridges in the Legacy area will require full closures at some point during the project. The Sam Rayburn Tollway Fourth Lane Project is projected to be complete in 2021.
