(May 23, 2011) Northbound Dallas Parkway will be closed just north of SH 121 on the weeknights of May 23 - 26 and May 31 - June 2. The frontage road will be closed each night at 9:00 p.m. and will reopen by 5:00 a.m. the following morning. The frontage road will be closed between the southwest-bound SH 121 frontage road and the northbound DNT exit ramp to Gaylord Parkway. (The exit ramp to Gaylord Parkway will not be closed.)
During this closure, northbound traffic on Dallas Parkway will be diverted onto the northeast-bound SH 121 frontage road to Preston Road where they can continue their journey north or u-turn to reach the southwest-bound SH 121 frontage road. Detour signs will be posted.
These road closures are part of NTTA’s Dallas North Tollway/Sam Rayburn Tollway interchange construction project. Motorists are urged to use caution in the construction zone and to choose an alternate route in advance.
