Collin County Outer Loop

The Collin County Outer Loop is a 55-mile planned multi-modal transportation facility that will ultimately go from the Denton/Collin County line, through cities including Celina, Weston, Anna, Melissa, Farmersville, Josephine and Royse City, to the Rockwall/Collin County line. The facility will include a freeway with a wide area in the center reserved as a future rail corridor.

Since 2000, the County has been in the process of planning for the facility starting with a corridor study and leading up to the identification of a preferred alignment. A diagram of the 500-foot wide right of way is shown below to illustrate how the facility is perceived to be utilized.

An overview map of the alignment is also shown below. You can also access the County's interactive map for more detail.

The freeway is being built in a phased approach. The construction of the service roads will be developed ahead of the freeway main lanes and the center will be reserved for the rail corridor.

STATUS, Summer, 2021

The Outer Loop is being developed in five segments, as can be seen on the overview map. Below is the most recent activity for each of the segments as of Summer 2021.

Segment 1: U.S. 75 to S.H. 121 (Between Anna and Melissa)

The County completed the two-lane roadway, which will function as the future westbound service road of the freeway, from US 75 to SH 121 in 2012.

Segment 2: FM 6 (between Nevada and Josephine) to Rockwall County line (E. of Royse City)

The technically preferred alignment was approved in 2009. No other activity has been completed on this segment.

Segment 3: Dallas Parkway (in Celina) to U.S. 75 (Between Anna and Melissa)

The County has completed a schematic for the future Outer Loop freeway from the Denton/Collin County Line to US 75 as well as concept designs for the future Outer Loop at the interchanges with US 75, Preston Rd/SH 289 and the Dallas North Tollway. Those documents can be found in the links below.

The concept plans for the interchanges at Preston Rd and the DNT are incorporated in the schematics.

Construction on the 2-lane roadway from just east of the Denton/Collin County line to SH 289 (Preston Rd) is anticipated to be completed in the summer of 2021. Construction started in March of 2021 on the 2-lane roadway from SH 289 (Preston Rd.) to FM 2478 (Custer Rd.). This construction is anticipated to be completed in the fall of 2022.

Right of Way acquisition is ongoing for the section between FM 2478 (Custer Rd.) and US 75. No construction timeline has been set, but the county anticipates continuing the 2-lane roadway to US 75 as soon as right-of-way acquisition is complete.

Segment 4: US 380 (in Farmersville) to FM 6 (Josephine)

The technically preferred alignment was approved in 2010. No other activity has been completed on this segment.

Segment 5: S.H. 121 (in between Anna and Melissa) to U.S. 380 in Farmersville

The technically preferred alignment was approved in 2006. No other activity has been completed on this segment.
