Drivers on the Dallas North Tollway may need to seek alternative routes as crews conduct maintenance work on two connector ramps.

The maintenance work will affect lanes on the north- and southbound DNT ramps connecting with eastbound traffic on the Sam Rayburn Tollway, according to a North Texas Tollway Authority news release.

Crews will begin closing the ramps nightly from 10 p.m.-5 a.m. starting Sept. 10. Work is expected to be completed by the morning of Sept. 12, weather permitting.

Detour routes will require drivers to exit onto the eastbound SRT access road during the designated times. NTTA will post signs prior to the closures.
