(March 30, 2011) The southwest-bound Sam Rayburn Tollway will be closed between Parkwood Boulevard and the Dallas North Tollway each night for two weeks starting Thursday night, March 31, and continuing through Tuesday night, April 12. The highway will close at 9:00 p.m. each night and is expected to reopen by 5:00 a.m. the following morning.
During these highway closures, all traffic on the southwest-bound Sam Rayburn Tollway will be diverted onto the SH 121 frontage road at the Parkwood exit ramp and will be able to re-enter the highway at the next entrance ramp. Detour signs will be posted.
These road closures are part of NTTA’s interchange construction project. Motorists are urged to use caution in the construction zone.
