Roadwork is underway in southeast McKinney to expand Spur 399 with a vision to eventually extend the highway around the city. The Texas Department of Transportation broke ground on a $157 million project this summer to expand the existing Spur 399 from four to six lanes. The project is one of three separate segments that aim to connect Spur 399 to US 380, TxDOT Public Information Officer Madison Schein said. Construction of the extension is estimated to cost $983 million in total to “address the congestion and improve mobility” in eastern Collin County, she said in an email. The second and third segments will construct an eight-lane freeway with frontage roads along McKinney National Airport’s east side. Officials expect to award a construction contract for the second segment in a few years, Schein said. Council member Justin Beller, whose district includes East McKinney, said construction is moving fast on the first segment. “They are aggressive with it, which is a good thing and a bad thing for those that live around it and those that have to drive through it,” he said. “But it means that they’re working to get this done as quick as possible, which will be a big relief for all of us who have to deal with the effects.”

current projects in McKinney, Beller said. “Thoroughfares like this are what’s going to make all that possible,” he said. “Gridlock is going to slow that down, and so this is a vital corridor for Collin County.”

Spur 399 and US 380 in the coming years, TxDOT officials said. Spur 399’s extension and the US 380 bypass are “massive” in providing access to communities like Princeton and Farmersville while supporting

The Spur 399 extension isn’t the only major project planned in Collin County. TxDOT officials are also planning the US 380 bypass, an eight-lane controlled access freeway through north McKin- ney. More than $8 billion is planned for projects on
