US 380 Denton County Feasibility Study


What is the purpose of the study?

Analyze potential alternative alignments for a limited access facility, including the existing alignment and new alignments, for US 380 & SL 288 from I-35 to Collin County line within Denton County.  This study assumes that the planned grade separated improvements from the US 380 from Loop 288 to West of CR 26 project  to be considered as the No-Build (do nothing) scenario.

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?

Spring 2018 – Study begins

Spring 2018-Winter 2018 – Data collection, alternatives development, and stakeholder meetings

January 2019 – Public open house meetings

Spring 2019-Winter 2020 – Alternatives studied and refined, narrow alternatives to a few alignments, stakeholder meetings

December 2020 – Virtual public meeting

Winter 2020-Fall 2021 – Alternatives continue to be studied and refined, stakeholder meetings, working toward identification of a single recommended alignment

Fall-Winter 2021 – Public Meeting

Winter 2021-Spring 2022 – Refine recommended alignment and document findings in a final feasibility report

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

Why is the study being conducted?

The County is growing…

Similar to Collin County, the population of Denton County is projected to grow from approximately 663,000 people (2010 Census) to over 3 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 Denton 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.
