(July 13, 2011) The SRT/DNT interchange closures scheduled for tonight, Wednesday, July 13, include the southwest-bound Sam Rayburn Tollway near the Dallas North Tollway and both directions of the Dallas Parkway frontage roads between SH 121 and Headquarters Drive. The closures begin at 9:00 p.m. tonight and will end by 5:00 a.m. tomorrow morning. The details of each closure are described below:
The southwest-bound Sam Rayburn Tollway (SRT) main lanes will be closed between Preston Road and Legacy Drive. Southwest-bound traffic will be diverted onto the SH 121 frontage road at Preston Road and will be able to re-enter the SRT Tollway near Legacy Drive.
The northbound and southbound Dallas Parkway frontage roads will be closed between SH 121 and Headquarters Drive. Frontage road traffic will be diverted to Parkwood Boulevard to use as an alternate route.
Motorists are urged to use caution in the construction zone and to choose an alternate route in advance.
These road closures are part of NTTA’s interchange construction project which is prompting a series of overnight closures that will occur each weeknight in July. Depending on the contractor’s schedule, a different combination of main lanes and/or frontage roads will be closed each night. Daily updates of each closure are available on www.ntta.org by clicking on “general lane and ramp closures” and the City of Frisco will announce each night’s closure as the information becomes available.
