(May 27, 2011) All lanes of Parkwood Boulevard will be closed underneath the Sam Rayburn Tollway each night starting Tuesday, May 31, and continuing through June 19. The road will close at 9:00 p.m. each night and will reopen by 5:00 a.m. the following morning.
During these closures, traffic on northbound Parkwood Boulevard will be diverted onto the northeast-bound SH 121 frontage road to Preston Road where they can continue their journey north or can u-turn back to Parkwood. Southbound traffic on Parkwood Boulevard will be diverted onto the southwest-bound SH 121 frontage road to Dallas Parkway where they can continue their journey south or can u-turn back to Parkwood. 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 and to choose an alternate route in advance.
