(November 10, 2011) The Sam Rayburn Tollway (SRT)/Dallas North Tollway (DNT) interchange closures scheduled for tonight, Thursday, November 10, include the southbound Dallas Parkway frontage road and the southwest-bound SH 121 frontage road. 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 southbound Dallas Parkway frontage road will be closed between Gaylord Parkway and the northeast-bound SH 121 frontage road. During this closure, all southbound traffic on Dallas Parkway will be directed to turn right onto Warren Parkway or Gaylord Parkway and then use Legacy Drive as a detour. Southbound traffic on the DNT will not be able to exit to SH 121 and should plan to exit earlier and use Legacy Drive as an alternative route. Residents of Stonebriar Creek Estates will need to use the entrance to their neighborhood on Legacy Drive.
The southwest-bound SH 121 frontage road will be closed between southbound Dallas Parkway and the exit ramp from the Sam Rayburn Tollway that is located just west of the DNT. During this closure, southwest-bound traffic on the frontage road will be detoured south onto Dallas Parkway and then right onto Legacy Drive in order to return to SH 121.
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 night in November. 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.
