Hwy 75-380 Interchange Undergoes Change

One of the busiest intersections in Collin County is about to get a little busier when the Texas Department of Transportation begins work on two-year, $25.6 million overhaul of the U.S. 75-U.S. 380 interchange smack dab in the middle of McKinney.

With this badly needed roadway reconstruction and widening, drivers may want to take heed that lane closings and delays will be unavoidable for the two-year project.

The 75-380 project involves adding two lanes each for north- and southbound traffic on U.S. 75 for a short distance in preparation of future road expansion plans. Also, the project will include lengthening entrance and exit ramps and adding an extra lane to service roads for both sides of the highway to handle increased traffic.

The project will unfold in three phases, with a timeline estimate based on a favorable number of “good-weather” days for construction crews:

• Phase One: Southbound lanes on U.S. 75, November through March 2009;
• Phase Two: Southbound U.S. 75 frontage road and continued construction on the U.S. 75 freeway lanes, March 2009-February 2010;
• Phase Three: Northbound U.S. 75 frontage road, U.S. 380 under U.S. 75, and finish work on U.S. 75 main lanes, February-November 2010.

Part of the project also includes moving entrance and exit frontage ramps further back from the U.S. 380 interchange to provide increased capacity.
