Various Closures Scheduled for Frontage Road and Tollway at SRT/DNT Interchange Friday Night through Monday Morning, February 25-28 

(February 24, 2011) NTTA’s construction of the Sam Rayburn Tollway/Dallas North Tollway interchange is triggering a series of overlapping frontage road and tollway closures beginning 9 p.m Friday night, February 25 , continuing throughout the weekend, February 26-27, until early Monday morning, February 28.  The details of each closure are described below:

Southbound Dallas Parkway will be closed between the SH 121 frontage roads starting at 9 p.m. Friday, February 25, and will remain closed throughout the weekend.  The frontage road is expected to reopen by 5 a.m. Monday morning, February 28.  During the closure, southbound traffic on Dallas Parkway will not be able to proceed straight onto Dallas Parkway or turn left onto northeast-bound SH 121.  Also, southwest-bound traffic on SH 121 will not be able to turn left onto southbound Dallas Parkway.  This means that traffic will not be able to use this intersection to enter the southbound Dallas North Tollway from the north or from the east.  Detour signs will be posted that divert traffic west to Legacy Drive which will take them south to the Dallas North Tollway.

The southwest-bound Sam Rayburn Tollway will be closed at the Dallas North Tollway starting at 9 p.m. Friday, February 25, and will remain closed throughout the weekend.  The highway is expected to reopen at 5 a.m. Monday morning, February 28.  During this highway closure, all traffic on the southwest-bound Sam Rayburn Tollway will be diverted onto the SH 121 frontage road prior to the Dallas North Tollway and will be able to re-enter the highway near Legacy Drive.  Detour signs will be posted.         

The northeast-bound SH 121 frontage road will be closed between Legacy Drive and Dallas Parkway starting at 11:45 p.m. Friday night, February 25.  The frontage road is expected to reopen by 5 a.m. Saturday morning, February 26.  During this closure, traffic on the northeast-bound Sam Rayburn Tollway will not be able to exit to the Dallas North Tollway.  Detour signs will be posted that divert traffic onto Legacy Drive which takes them south to the Dallas North Tollway.

The northeast-bound Sam Rayburn Tollway will be closed at the Dallas North Tollway starting at 11:45 p.m. Friday night, February 25.  The highway is expected to reopen by 5 a.m. Saturday morning, February 26.  During this highway closure, all traffic on the northeast-bound Sam Rayburn Tollway will be diverted onto the SH 121 frontage road prior to the Dallas North Tollway and then must use Legacy Drive and Headquarters Drive to continue eastward before being be able to re-enter the highway east of Parkwood Boulevard.  Detour signs will be posted.

The NTTA has provided a map of these closures and the detour routes. Motorists are urged to use caution in the construction zone.
