October 5 overnight road closures, detours around the Sam Rayburn Tollway/Dallas North Tollway Interchange 

(October 5, 2011) The Sam Rayburn Tollway (SRT)/Dallas North Tollway (DNT) interchange closures scheduled for tonight, Wednesday, October 5, include the northbound DNT, southbound Dallas Parkway and the southwest-bound SH 121 frontage road.  The closures begin at 9:00 p.m. or 10:00 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 starting at 9:00 p.m.  During this closure, northbound traffic will be diverted onto the northbound Dallas Parkway frontage road at Headquarter Drive and will be able to re-enter the DNT at Gaylord Parkway.

The southbound Dallas Parkway frontage road will be closed between Gaylord Parkway and the southwest-bound SH 121 frontage road starting at 10:00 p.m.  During this closure, all southbound traffic will be directed to turn right onto Warren Parkway or Gaylord Parkway and then use Legacy Drive as a detour.  Southbound traffic on the Dallas North Tollway will not be able to exit to SH 121 and should plan to exit earlier and use Legacy Drive as an alternative route.  Residents of Stonebriar Creek Estates will need to use their entrance on Legacy Drive. 

The southwest-bound SH 121 frontage road will be closed between Parkwood Boulevard and the southwest-bound SRT exit ramp to Legacy Drive starting at 10:00 p.m.   Southwest-bound traffic wanting to enter the southwest-bound SRT can continue on the frontage road to that entrance ramp, but all other traffic will be detoured either north or south on Parkwood Boulevard depending on their destination.  Southwest-bound traffic needing to go north on Dallas Parkway or the DNT, should go north on Parkwood Boulevard and then west on Gaylord Parkway.  Traffic needing to continue southwest on SH 121 or to go south on Dallas Parkway or the DNT should go south on Parkwood Boulevard to Headquarters Drive and follow the detour signs.

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.
