Traffic to Switch Lanes on U.S. 75 near Sam Rayburn Tollway All traffic on U.S. 75 in Collin County will soon be shifted onto the southbound side of the highway for approximately one mile near the Sam Rayburn Tollway (SRT) interchange.
This traffic switch is expected to occur at the end of September 2009. The NTTA will place electronic message signs to alert drivers prior to the switch.
When the switch occurs, traffic on northbound U.S. 75 will be shifted onto the southbound side of the highway in the northern Allen, Fairview and southern McKinney area to accommodate construction of the Sam Rayburn Tollway/U.S. 75 interchange.
Drivers in this area of U.S. 75 still will have two lanes of travel in both directions. A concrete traffic barrier will separate southbound cars from northbound cars.
The following information will help motorists better navigate the traffic switch:
- As northbound U.S. 75 drivers approach Ridgeview Drive, their lanes will start shifting to the southbound side.
- When northbound U.S. 75 drivers pass Ridgeview Drive, their lanes will be completely shifted to the southbound side of U.S. 75.
- The traffic switch will be approximately one mile in length.
- Just north of the Sam Rayburn Tollway (formerly State Highway 121 and still labeled that way on highway signs), the northbound lanes will return to the northbound side of U.S. 75.
- The exit off U.S. 75 to Highway 5 will be moved approximately one-quarter of a mile south of its current location.
The NTTA is coordinating the traffic switch with the Texas Department of Transportation and the City of McKinney. The switch will last an estimated three to five months.
This traffic switch is the first of three lane movements on U.S. 75 that drivers will experience before the new four-level interchange is complete and scheduled to open to traffic in January 2011. Details on the other traffic switches will be provided in the future.
“We realize these traffic switches take time to get used to, and we thank drivers for their patience,” said Elizabeth Mow, NTTA director of project delivery. “The best thing for drivers to do is slow down, pay attention to the signs, and be extra attentive in the work zone.”
