Great Things Happen in Fours




If good things happen in threes, great things happen in fours!

Fourth lanes in each direction are now open on portions of the Dallas North Tollway (DNT) and on the President George Bush Turnpike (PGBT) between State Highway 78 and the tollway. That means more traffic capacity for a smoother commute.

And soon, more of our roads will join the fourth-lane wave.

Construction is underway to stretch the PGBT’s fourth lane from the DNT to Interstate 35E. And, we’re working to add a fourth lane in each direction to the whole length of the Sam Rayburn Tollway. Here’s what you need to know about how these projects may affect your commute.

Sam Rayburn Tollway

Crews are working day and night throughout the 26-mile Sam Rayburn Tollway (SRT) corridor. They’re removing the topsoil and sod to make way for the new lane in each direction. They’re working in the median between concrete barriers. However, please be aware that trucks will be entering and leaving the work site regularly.

The toll road crosses above several city streets, and additional work must be done on the toll road’s bridges above those streets to accommodate the new lanes. Some of the work will require full overnight closures of those intersections. Crews are working overnight to decrease the impact to drivers. Look for work crews near the following intersections:

  • Hillcrest Road/Rasor Boulevard
  • Legacy Drive
  • Josey Lane/Main Street
  • Castle Hills Drive/Standridge Drive
  • Hebron Parkway

Crews are now preparing to build the columns and supports for the bridge beams. Then they will pour concrete for the new lanes. Be sure to check the website for intersection closure information.

All the work to add lanes to the SRT is anticipated to be complete in late 2021.

President George Bush Turnpike

Along with construction to stretch the fourth lane on PGBT from I-35E to the DNT, you can look forward to some smoother pavement.  Crews removed the top layer of pavement on the eastbound main lanes and ramps between Frankford Road and Midway Road in late March.

For the next few weeks, crews will continue working overnight to resurface those lanes with the new pavement and replace the lane stripes. These pavement improvements will also enhance safety by increasing the visibility of lane stripes.

The same pavement improvements on the westbound lanes and ramps between Midway Road and Frankford Road are scheduled in April. This work will also be completed overnight and on weekends.

As always, we will announce lane or ramp closures via social media, and information will be posted on and We appreciate your patience during the ongoing improvements.
