U.S. 380 Bypass

Project Overview

The proposed TxDOT project for the U.S. 380 Bypass would provide an eight-lane freeway with frontage roads to manage congestion and east-west mobility, connectivity, traffic operations, and safety. This project is necessary because population growth within Collin County has resulted in traffic volumes that exceed the capacity of U.S. 380 between Coit Road and FM 1827, resulting in congestion, reduced mobility and higher crash rates than similar roadways in the region.

Project History

  • 2016 | Collin County Commissioner Court identified U.S. 380 as a priority project for a limited Access Roadway (Freeway) study. They did not specify a route for development.
  • 2017 - 2020 | TxDOT conducted a Feasibility Study and recommended U.S. 380 for the building of a freeway. At the end of the study, TxDOT recommended the construction of a freeway (U.S. 380 Bypass) and came up with 5 different alignment segments (A - E) on which they would like public input.
  • 2020 - Current | TxDOT is gathering pubic input and conducting Environmental Impact Studies (EIS) required by the National Environmental Policy Act (NEPA), on all 5 segments.
