As part of the ongoing TxDOT project to widen U.S. 75 from the Sam Rayburn Tollway to White Avenue in McKinney, the Texas Department of Transportation has informed the City of McKinney that the southbound on-ramp to the main lanes of U.S. 75 near Rockhill Road has been closed to allow construction in the area to continue. It will be replaced by a new on-ramp that will not be open until later this year.

In the meantime, drivers can continue south on the frontage road past North Brook Drive and Country Club Drive to the next on-ramp located south of Eldorado Parkway. Southbound frontage road drivers are encouraged to pay close attention to new detour signs that have been placed near North Brook Drive directing traffic to keep left in order to continue on the southbound frontage road.

Because construction can cause longer than normal wait times at some intersections, drivers are encouraged to seek alternate routes, if possible.

As a reminder, this TxDOT construction project to widen U.S. 75 to four main lanes in each direction and three frontage road lanes in each direction will provide much needed extra capacity through McKinney. The project is anticipated to be complete in January 2016.
