Traffic Patterns Change in Collin County to Accommodate Sam Rayburn Tollway Interchange Construction

Several traffic pattern changes along the Sam Rayburn Tollway (SRT) and Dallas North Tollway (DNT) will occur over the next 60 to 90 days to allow crews to continue their progress on both major interchanges at U.S. 75 and the DNT, now under construction along the SRT corridor.

In the coming weeks at the SRT/DNT interchange, an exit ramp off the northbound DNT will be closed in Frisco:

• On Saturday, Aug. 21, the northbound DNT exit ramp to Gaylord Parkway/Warren Parkway in Frisco will be closed for 100 consecutive days (through November 30) so the contractor can remove the old tolling structure, re-grade and reconstruct the ramp, and construct a new all-electronic toll gantry.

At the new SRT/U.S. 75 (Central Expressway) in Allen, Fairview and McKinney, traffic within the interchange work zone will be shifted onto new pavement in stages, making the drive through that area more enjoyable for motorists.

Two major changes in traffic patterns near the SRT/U.S. 75 interchange are listed below along with their anticipated time frames: 

• In late August or early September 2010, all traffic on U.S. 75 within the project limits will be shifted onto the northbound side of the highway. Although the lanes will be shifted, vehicles still will have two lanes of travel in both directions on U.S. 75.  This traffic shift will continue until the end of 2010, when traffic on U.S. 75 is expected to be routed into its final, regular configuration.

• By late October 2010, two major bridges – one connecting southbound U.S. 75 to southwest-bound SRT and another connecting northeast-bound SRT to northbound U.S. 75 – are expected to be complete and open to traffic.
