Motorists driving north into McKinney on U.S. 75 (Central Expressway) will need to exit earlier in order to reach Eldorado Parkway from April 1 through 5 p.m. July 1.

Starting at 7:30 p.m. Sunday, April 1, the Texas Department of Transportation (TxDOT) will close the exit ramp off northbound U.S. 75 to access Eldorado Parkway and the ramp to Eldorado Parkway from the Sam Rayburn Tollway’s (SRT’s) direct-connector. The closure will remain in effect through 5 p.m. July 1.

Northbound motorists on both U.S. 75 and the SRT seeking to access Eldorado Parkway will exit earlier and continue along the northbound U.S. 75 frontage road to Eldorado or their chosen destination.

The closure is part of the massive U.S. 75 widening project under way in McKinney. A TxDOT press release said that the closure is necessary so the contractor can begin the first stage of reconstruction of the northbound U.S. 75 frontage road, south of Eldorado Parkway.

The widening project will add two lanes in each direction on the U.S. 75 main lanes, including one in each direction on the frontage roads, giving the highway a total of eight main lanes and six frontage road lanes.

This will add needed capacity to U.S. 75 and is expected to stay ahead of the explosive population growth in Collin County. Listed as one of the fastest-growing counties in the nation, Collin County grew by more than 61 percent between 2000 and 2009.

“Frisco and McKinney are two of the fastest growing cities in the nation and the challenge to meet transportation needs has never been greater,” Barry Heard, P.E., Collin County Interim Area Engineer, said in a press release.

This is one of five projects either under way, nearing completion or just starting on the U.S. 75 corridor through McKinney from SH 121 to Melissa Road. This project is expected to be substantially complete in the summer of 2015.

TxDOT would like to thank area drivers for their patience and cooperation as crews work diligently to complete this vital project as soon, and as safely, as possible.
