Collin County completes Outer Loop segment connecting Celina, McKinney
Diving in deeper
Schematic work, construction plan preparation and construction management was completed by engineering firm BGE, RPM xConstruction served as the contractor, and engineering consultancy firm Terracon completed materials testing for the project, Collin County Director of Engineering Clarence Daugherty said at a Nov. 3 Collin County Commissioners Court meeting. Construction on the project, which was funded by the county’s 2018 bond, began in February 2024 and had a projected completion of March 2026. The project’s actual completion is November 2025, which is more than 3 months in advance of the projected timeline. “We do appreciate it,” Daugherty said. “When you can get a job done before schedule, it’s pretty unusual in this day and time.”
The Collin County Toll Road Authority directed the development of the segment with support from Collin County’s Department of Engineering. “We’re tremendously excited to open this new segment of the Outer Loop,” Collin County Judge Chris Hill said in the release. “This roadway will improve mobility and reduce travel times across the fast-growing northwest corridor of Collin County.” Segment 3C spans from Custer Road to US 75, and connects to previously completed sections of the Outer Loop.
A segment of the Collin County Outer Loop connecting Celina to north of McKinney has been completed and opened to the public, according to a news release. The two-lane roadway created a complete connection from Dallas North Tollway in Celina to US 75 just north of McKinney. The section officially opened to the public Nov. 7. The segment of roadway completed, dubbed Segment 3C by county officials, will serve as an east-west connection that will enhance regional connectivity and relieve congestion on other major roadways, the release states.

The Collin County Outer Loop is a planned 53-mile roadway through north and east Collin County, and will connect to both the Denton County line and the Rockwall County line. The ultimate planned configuration of the Outer Loop will include a 10-lane freeway with ramps as well as two-lane service roads in each direction, county documents show. The newly completed segment will serve as a future service road and design work for the second service road along that segment is expected to begin in 2026, Daugherty said.
