(September 14, 2011) The closures scheduled for tonight, Wednesday, September 14, include the southbound Dallas North Tollway (DNT), northbound Dallas Parkway, the southwest-bound SH 121 frontage road, and the northeast-bound SH 121 frontage road.  The closures begin at 9:00 p.m. tonight and will end by 5:00 a.m. tomorrow morning.  The details of each closure are described below:

The southbound Dallas North Tollway main lanes will be closed between SH 121 and Headquarters Drive in Plano.  Southbound traffic will be diverted onto the southbound Dallas Parkway frontage road at SH 121 and will be able to re-enter the DNT at Headquarters Drive in Plano.

The northbound Dallas Parkway frontage road will be closed between Headquarters Drive in Plano and IKEA Drive in Frisco.  Northbound traffic will be diverted east on Headquarters Drive to Parkwood Boulevard in order to continue  north. 

The southwest-bound SH 121 frontage road will be closed between Parkwood Boulevard and Legacy Drive.  Southwest-bound traffic will be detoured either north or south on Parkwood Boulevard depending on their destination.  Traffic needing to go north on Dallas Parkway or the DNT, should go north on Parkwood Boulevard and then west on Gaylord Parkway.  Traffic needing to continue southwest on SH 121 or the Sam Rayburn Tollway, or to go south on Dallas Parkway or the Dallas North Tollway should go south on Parkwood Boulevard and then west on Headquarters Drive and follow the detour signs.

The northeast-bound SH 121 frontage road will be closed between Dallas Parkway and Parkwood Boulevard.  Northeast-bound traffic will be diverted south on Dallas Parkway, left onto Headquarters Drive, and then north on Parkwood Boulevard in order to return to SH 121.

Motorists are urged to use caution in the construction zone and to choose an alternate route in advance.

These road closures are part of NTTA’s interchange construction project which is prompting a series of overnight closures that will occur each weeknight in September.  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.
