US 380 Collin County Feasibility Study

Project Map


What is the purpose of the study?

Analyze potential roadway alternatives, including the existing alignment and new alignments, for US 380 through Collin County from the Denton County line to the Hunt County line.

What is a feasibility study?

A feasibility study is one planning tool that TxDOT uses when a project is in the very early stages of development. It helps determine if the project should move on to more advanced phases of project development such as more in-depth environmental analysis, public involvement, schematic design and right-of-way mapping.  

The reason this type of study is done is to identify high level or critical elements of engineering, impacts to stakeholders and the public, and the economic feasibility of potential new roadways or improvements to existing roadways.

Feasibility studies are not intended to result in detailed design, environmental analysis, or cost estimates.

What will be evaluated in this feasibility study?

The study team will consider projected regional traffic, existing and planned developments, stakeholder input and the impact on the economy and environment. 

What are expected project milestones?

Summer 2017 – Study begins

Spring 2018 and Fall 2018 – Public open house meetings will be held to discuss the project and gather feedback from the public

Spring 2019 – Project implementation plan finalized that would include a recommended alignment(s)

*Please note that the project schedule is subject to change. 

Why is the study being conducted?

The County is growing…

The population of Collin County is projected to grow from just under 800,000 people (2010 Census) to over 3.8 million people in 2050, according to the Texas Demographic Center.*

*Assume the 2000-2010 Migration scenario for 2014 Texas Population Projections

More and more land in the County is being preserved for developments.

The study team is working with Collin County and cities in the study area to identify land which has been purchased and right of way that is preserved for existing or future planned residential or commercial development.  As the County’s population grows, the options to build a new roadway or expand the existing US 380 become more limited and potential impacts to residential and commercial developments increase.  The feasibility study will identify a roadway alignment or alignments to serve as a blueprint for City staff to begin preserving land now. 

When will construction begin?

There are many steps that must be completed after this project before construction could begin such as a more in-depth environmental analysis and public involvement, schematic design, right-of-way mapping and detailed roadway design.
