(June 1, 2011) The northbound and southbound Dallas Parkway frontage roads will be closed between Headquarters Drive in Plano and SH 121 every weeknight in June. The frontage roads will close each weeknight at 9:00 p.m. and then reopen the following morning at 5:00 a.m.
During these closures, motorists on northbound Dallas Parkway will be diverted east onto Headquarters Drive and then north on Parkwood Boulevard to reach the SH 121 frontage roads. Motorists on southbound Dallas Parkway will be diverted onto the southwest-bound SH 121 frontage road and then south on Legacy Drive to reach Dallas Parkway. 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.
