(April 20, 2011) Both directions of the SH 121 frontage roads will be closed near the Dallas North Tollway (DNT) every night for the next week except Easter weekend.  The frontage roads will be closed the nights of April 20 to 22 and April 25 to 27.  The frontage roads will close at 9:00 p.m. each night and are expected to reopen by 6:00 a.m. the following morning.  NTTA has provided a map of these closures and the detour routes... view the map.  

The northeast-bound SH 121 frontage road will be closed between Legacy Drive and Dallas Parkway.  During the closures, northeast-bound traffic will be diverted onto Legacy Drive where they can reach the Dallas North Tollway or go north on Dallas Parkway to continue  on the northeast-bound SH 121 frontage road.  Detour signs will be posted.

The southwest-bound SH 121 frontage road will be closed between the Dallas Parkway frontage roads.  During the closures, southwest-bound traffic will be diverted north on Dallas Parkway to make a u-turn at Gaylord Parkway and return south on Dallas Parkway to access the Dallas North Tollway or to continue on the southwest-bound SH 121 frontage road.  Detour signs will be posted. 

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.
