(October 20, 2011) The Sam Rayburn Tollway (SRT)/ Dallas North Tollway (DNT) interchange closures scheduled for tonight, Thursday, October 20, include the northbound Dallas North Tollway and the southbound Dallas Parkway 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 northbound Dallas North Tollway main lanes will be closed between Headquarters Drive in Plano and Gaylord Parkway in Frisco. During this closure, northbound traffic will be diverted onto the northbound Dallas Parkway frontage road at Headquarters Drive and will be able to re-enter the DNT at Gaylord Parkway.
The southbound Dallas Parkway frontage road will be closed between the southwest-bound SH 121 frontage road and Headquarters Drive in Plano. During this closure, all southbound traffic will be detoured onto the southwest-bound SH 121 frontage road and then south on Legacy Drive to return to Dallas Parkway.
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 October. 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.
