(March 29, 2011) The northeast-bound SH 121 frontage road will be closed between Legacy Drive and Dallas Parkway Tuesday night, March 29, and Wednesday night, March 30. The frontage road will close at 9:00 p.m. each night and is expected to reopen by 6:00 a.m. the following morning. During these closures, 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.
These road closures are part of NTTA’s interchange construction project. Motorists are urged to use caution in the construction zone and to plan an alternate route in advance.
