(November 15, 2011) The Sam Rayburn Tollway (SRT)/Dallas North Tollway (DNT) interchange closures scheduled for tonight, Tuesday, November 15, include the southwest-bound SRT and the northeast-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 southwest-bound Sam Rayburn Tollway main lanes will be closed between Parkwood Boulevard and Legacy Drive. Southwest-bound traffic will be diverted onto the southwest-bound SH 121 frontage road at Parkwood Boulevard and will be able to re-enter the SRT at Legacy Drive.
The northeast-bound SH 121 frontage road will be closed between the Dallas Parkway frontage roads. Northeast-bound traffic will be detoured right onto southbound Dallas Parkway and then can turn around at Headquarters Drive 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.
