(July 14, 2011) The SRT/DNT interchange closures scheduled for tonight, Thursday, July 14, include the northeast-bound Sam Rayburn Tollway (SRT) near the Dallas North Tollway (DNT), the southbound DNT near the SRT, and the northbound Dallas Parkway frontage road between Headquarters Drive and Gaylord Parkway. 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 northeast-bound Sam Rayburn Tollway main lanes will be closed between Legacy Drive and Preston Road. Northeast-bound traffic will be diverted onto the SH 121 frontage road at Legacy Drive and will be able to re-enter the SRT Tollway east of Preston Road.
The southbound Dallas North Tollway main lanes will be closed between the SRT and Headquarters Drive in Plano. Southbound traffic will be diverted onto the southbound Dallas Parkway frontage road at SH 121 and will be able to re-enter the DNT Tollway at Headquarters Drive.
The northbound Dallas Parkway frontage road will be closed between Headquarters Drive in Plano and Gaylord Parkway in Frisco. Frontage road traffic will be diverted to Parkwood Boulevard to use as an alternate route. SH 121 frontage road traffic that crosses northbound Dallas Parkway will not be affected.
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.
