Sam Rayburn Tollway Fourth Lane

Sam Rayburn Tollway Fourth Lane Project Description

Improvements to Sam Rayburn Tollway (SRT) include constructing an additional lane in each direction, in the center median, along the entire 26-miles of the SRT, from west of Denton Tap Road to U.S. 75. Ramp improvements will also be made between the Dallas North Tollway (DNT) and Preston Road to separate traffic for motorists exiting from northbound SRT to Preston Road and motorists entering SRT from DNT. Auxiliary lanes will be added in various locations along the corridor to improve ramp merging areas.

As part of the North Texas Tollway Authority’s (NTTA) public involvement and environmental analysis processes, two community meetings were held in February 2017. In July 2017, a Public Hearing was held to present the project and results of the environmental analysis, and to receive formal comments from those in attendance. Comments were accepted until August 9, 2017.

The presentation shown during the Public Hearing is available here. View the draft schematic maps here.

All comments were reviewed and responded to by NTTA. That information, a Public Hearing Summary and other project details are included in the Sam Rayburn Tollway Fourth Lane Widening Categorical Exclusion Documentation.

Design is in progress and construction is anticipated to begin late-2018 and is expected to open to traffic in 2021.
