Design work to begin on Collin County Outer Loop segment between Preston and Custer roads


The county has taken another step toward planning for the Collin County Outer Loop as design work is moving forward.

During a Collin County Commissioners Court meeting June 24, commissioners gave the go ahead for the county’s engineering department to enter into an agreement with Jacobs Engineering Group.

According to the agreement, the engineering group will design the Outer Loop segment between Preston and Custer roads. Design work is expected to take about 18 months to complete, and the cost is estimated to be upward of $860,000.

Additionally, construction along this stretch of roadway is estimated to cost more than $10.2 million. But, depending on the market at the time of construction, this price could fluctuate, said Clarence Daugherty, the Collin County director of engineering.

The engineering firm recently completed schematics for the Outer Loop’s main lanes and service roads from the Dallas North Tollway east to Preston.

Once complete, the Outer Loop is proposed to extend east from the Denton County and Collin County line then south to Rockwall County. The loop is expected to help relieve traffic on US 380 and SH 78.

According to Daugherty, bids for the construction of the freeway are being analyzed by county staff and will be brought to commissioners for consideration in the near future.

  1. Good start. How about a small map detailing where the road is going to be, along with future plans?

    • Hi Ralph,

      Thank you for the suggestion. We’ve attached a map to the article. I hope this helps.

    I’ve thought that about many of these articles I read here. Sometimes they have maps, but many times I’m left frustrated about where exactly they are talking about. Maps should be standard fare in articles like this.

    • Hi Michael,

      We’ve attached a map of the proposed Collin County Outer Loop to the article. I hope this helps.


  3. How about adding public transit instead of more highways? Studies have shown that increasing road capacity actually makes traffic congestion worse. Google the Hidden Brain podcast.

    • adding Road capacity makes traffic not get any better, but sadly the public transit is not going to happen because currently none of the cities are part of DART. Instead they are with some shuttle only service to disabled people. Mckinney and allen should just join DART and extend the red line to mckinney.
