The details
Construction is expected to start this summer and finish in early 2029, officials said. The project will focus on reconstructing and widening Spur 399 from its current four-lane configuration. The project also plans for a new grade-separated interchange at Spur 399’s intersection with Stewart Road.
The project is expected to cost $182 million in total and will add lanes between US 75 and Steward Road. TxDOT awarded a construction contract to Webber Construction in December, according to a progress report from TxDOT’s Dallas district office.
The project is one portion of a larger plan to extend Spur 399 around McKinney National Airport and connect the road to US 380.
What they’re saying
TxDOT Executive Director Marc Williams said the project is a “huge step” toward improving mobility and easing congestion in Collin County. The Spur 399 corridor has been identified as one of the most congested roadway segments in Texas, he said.
“Keeping Texans moving and out of traffic faster and safer is the goal,” Williams said. “That’s why I’m excited to be here today with you breaking ground on a project that will help keep this region moving.”
TxDOT is also planning the US 380 bypass project that will add a new eight-lane freeway routed through North McKinney. The first contract for that project is expected to be awarded in 2027, according to officials.
“Today’s event marks not only the beginning of the Spur 399 project, but also the kickoff of more than $8 billion of projects on [Spur 399] and US 380 that are planned for the years to come,” Williams said.
Collin County Commissioner Duncan Webb said the US 380 and Spur 399 projects are two of the “most significant” transportation developments in Collin County’s history. The projects have been a number one priority for the county and TxDOT to address, he said.
As construction begins, drivers will experience some delays and other impacts over the next three and a half years of construction, he said.
“However, the finished product will be worth it,” Webb said.
Quote of note
McKinney City Council members Justin Beller and Patrick Cloutier, Mayor-elect Bill Cox and McKinney Engineering Director Gary Graham attended the ceremony. Cloutier said the Spur 399 extension will offer a new connection between US 75 and US 380.
“What Spur 399 is going to allow people to do is get up north quicker [and] get out west quicker,” Cloutier said. “It's going to allow us to repurpose [SH5].”
Ownership of SH 5, which is a TxDOT road, will be transferred to the city once Spur 399 is connected to US 380, Cloutier said. SH 5 currently has few stoplights, no sidewalks and poor pedestrian crossings, Cloutier said.
Plans are underway to reconstruct SH 5 between McMakin Street and Power House Street, according to McKinney’s website. The project, which is being led by TxDOT, will include new sidewalks, turn lanes at specific intersections and improved stormwater systems.
“This is going to make McKinney a safer place,” Cloutier said. “It’s going to be an easier place for our neighbors to travel through. Roads are boring but this is a big day for McKinney, Texas.”
