(November 17, 2011) The Sam Rayburn Tollway (SRT)/Dallas North Tollway (DNT) interchange closure scheduled for tonight, Thursday, November 17, includes the northeast-bound SH 121 frontage road. The closure begins at 9:00 p.m. tonight and will end by 5:00 a.m. tomorrow morning. The details of the closure are described below:
The northeast-bound SH 121 frontage road will be closed between Dallas Parkway and Parkwood Boulevard. Northeast-bound traffic will be diverted south on Dallas Parkway, left onto Headquarters Drive, and then north on Parkwood Boulevard 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.
