Various main lanes and frontage roads closed at DNT/SRT Interchange every weeknight in July 

(July 11, 2011) Ongoing construction of the Dallas North Tollway/Sam Rayburn Tollway interchange will prompt a series of overnight closures each weeknight in July.  Depending on the contractor’s schedule, each night a different combination of main lanes and/or frontage roads will be closed generally starting at 9:00 p.m. and ending by 5:00 a.m. the following morning.  Daily updates of each closure are available on www.ntta.org by clicking on “general lane and ramp closures,” and the city will announce each night’s closure as the information becomes available.

The closures scheduled for tonight, Monday, July 11, are as follows:

The northbound Dallas North Tollway main lanes will be closed between Headquarters Drive in Plano and Gaylord Parkway.  Northbound traffic will be diverted onto the northbound Dallas Parkway frontage road and will be able to re-enter the DNT Tollway at Gaylord Parkway.

The southbound Dallas Parkway frontage road will be closed between SH 121 and Headquarters Drive.  Southbound frontage road traffic will be diverted to Parkwood Boulevard to use as an alternate route. 

The northeast-bound Sam Rayburn Tollway main lanes will be closed between Legacy Drive and Parkwood Boulevard.  Northeast-bound traffic will be diverted onto the SH 121 frontage road and will be able to re-enter the SRT Tollway east of Parkwood Boulevard. 

These road closures are part of NTTA’s interchange construction project.  Motorists are urged to use caution in the construction zone and to choose an alternate route in advance.
