(October 31, 2011) The Sam Rayburn Tollway (SRT)/Dallas North Tollway (DNT) interchange closure scheduled for tonight, Monday, October 31, includes the northbound Dallas Parkway frontage road. The closure begins at 9:00 p.m. tonight and will end by 5:00 a.m. tomorrow morning.
The northbound Dallas Parkway frontage road will be closed between Headquarters Drive in Plano and SH 121. During this closure, northbound traffic will be diverted east onto Headquarters Drive, north on Parkwood Boulevard, and then southwest on the SH 121 frontage road to return to Dallas Parkway.
Motorists are urged to use caution in the construction zone and to choose an alternate route in advance.
This road closure is part of NTTA’s interchange construction project which is prompting a series of overnight closures that will occur each night in October and November. 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.
