Closures, detours happening tonight, September 28, around the Sam Rayburn Tollway/Dallas North Tollway Interchange 

(September 28, 2011) The Sam Rayburn Tollway/Dallas North Tollway interchange closures scheduled for tonight, Wednesday, September 28, include northbound Dallas North Tollway for part of the time, northbound Dallas Parkway for part of the time, 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. and reopening sometime in the middle of the night.  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.  Once the northbound main lanes are reopened in the middle of the night, the northbound Dallas Parkway frontage road will be closed as described below.

The northbound Dallas Parkway frontage road will be closed between Headquarters Drive in Plano and SH 121 starting at some point in the middle of the night once the northbound DNT is opened.  Northbound traffic will be diverted east on Headquarters Drive to use Parkwood Boulevard to continue their journey north.  The frontage road will reopen by 5:00 a.m. tomorrow morning.

The southbound Dallas Parkway frontage road will be closed between Gaylord Parkway in Frisco and Headquarters Drive in Plano 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 the entrance to their neighborhood on Legacy Drive. 

The southwest-bound SH 121 frontage road will be closed between southbound Dallas Parkway and the southwest-bound SRT exit ramp to Legacy Drive starting at 10:00 p.m.  Southwest-bound traffic needing to continue southwest on SH 121 or the Sam Rayburn Tollway or to go south on Dallas Parkway or the Dallas North Tollway should go south on Parkwood Boulevard to Headquarters Drive and follow the detour signs.  (Southwest-bound traffic needing to go north on Dallas Parkway or the Dallas North Tollway will be able to turn right onto Dallas Parkway as usual.) 

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 September.  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.
