Who’s Prowling Around in the Night?



Traveling at night can be eerie, especially if you let your imagination spin tales about what – or who – may be lurking in the dark, beyond the road.

Though you won’t see zombies pop out from behind a toll gantry, you definitely shouldn’t panic if you see our maintenance or construction crews working at night. They’re the good guys and gals.

But why are they working in the dark?

We schedule larger maintenance and construction projects overnight, when possible, usually between 10 p.m. and 5 a.m. to minimize disruptions to traffic. Only night owls know they’re there, and our roads are open and ready to go before the morning rush.

So if you happen to see the bright neon vests of maintenance teams or construction crews after the sun goes down, don’t be alarmed. Instead, slow down, give them a little room, stay alert for temporary lane reconfigurations and drive easy knowing they are working to make our roads safer and your commute more convenient.

To know ahead of time where these crews might be, visit our website at and click the “Scheduled Lane Closures” link on our homepage. You can also follow us on Twitter at @NTTATravelAlert for the latest traffic updates.

As always, if you have any questions or concerns related to our work to improve the Sam Rayburn Tollway or the President George Bush Turnpike, please contact us at You can also reach us at 972-628-3134.
