The Collin County Commissioners Court celebrated the official opening of the first section of the Collin County Outer Loop on Monday morning, along with special guest Congressman Sam Johnson, local dignitaries and area residents, county staff members and representatives of the engineering and construction firms responsible for the first segment of roadway.

Several dozen people, along with a number of media representatives, were in attendance for the picture-perfect event.

The Outer Loop project is a multi-jurisdictional construction project, first conceived by the Commissioners Court in 2002 in response to the rapid and projected population and commercial growth in Collin County.

It will eventually be a thoroughfare circling the northern and eastern parts of Collin County, linking up similar loops in Rockwall County (to the south) and Denton County (to the west).

Segment One, a two-lane concrete roadway extending 4.6 miles, was recently completed. Designed to alleviate traffic on State Highway 121 traveling to U.S. 75, this initial segment of the Outer Loop took 18 months to complete at an approximate cost of $21 million. It was mostly funded through Regional Toll Road revenues.
