(August 15, 2011) The Sam Rayburn Tollway(SRT)/Dallas North Tollway (DNT) interchange closures scheduled for tonight, Monday, August 15, include the southwest-bound Sam Rayburn Tollway near the DNT, southbound Dallas Parkway south of SH 121, and Headquarters Drive near the DNT.  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 southwest-bound Sam Rayburn Tollway main lanes will be closed between Ohio Drive and Legacy Drive.  During this closure, southwest-bound traffic on the SRT will be diverted onto the southwest-bound SH 121 frontage road at Ohio Drive and will be able to reenter the SRT at Legacy Drive.

Southbound Dallas Parkway will be closed between SH 121 and Headquarters Drive in Plano.  During this closure, motorists on southbound Dallas Parkway will be detoured east on the SH 121 frontage road to Parkwood Boulevard to continue their journey south.
