(August 11, 2011) The SRT/DNT interchange closures scheduled for tonight, Thursday, August 11, include the northeast-bound Sam Rayburn Tollway near the DNT and the southbound Dallas North Tollway near the SRT. 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 the Dallas North Tollway and Parkwood Boulevard. Northeast-bound traffic will be diverted onto the northeast-bound SH 121 frontage road at the exit to the Dallas North Tollway and will be able to re-enter the SRT at Parkwood Boulevard.
The southbound Dallas North Tollway main lanes will be closed between SH 121 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 at Headquarters Drive.
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 August. 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.
