About the Project

The Texas Department of Transportation (TxDOT) is preparing a corridor study, design schematic, environmental assessment, and public involvement through environmental clearance for US 75 from I-635 to SH 121 in Dallas and Collin Counties.  The proposed project will include a corridor study and preliminary engineering through Federal Highway Administration (FHWA) design schematic approval and FHWA environmental clearance for alternatives to improve mobility in the US 75 corridor from IH 635 to SH 121 within the Cities of Dallas, Richardson, Plano, Allen and Fairview. 

TxDOT will coordinate with local governments, the North Central Texas Council of Governments (NCTCOG), Dallas Area Rapid Transit (DART), local cities and counties, and other State and federal agencies to ensure that the recommended solution is consistent with local, regional and state planning efforts.   

Project Purpose
The purpose of this project is to identify alternatives and solutions to address mobility needs in the corridor and to minimize the impacts in the study area.  As part of the study, detailed engineering drawings will be developed to depict the recommended solution and an environmental document will be developed to satisfy Federal Highway Administration (FHWA) requirements.

Project Need
This project will address long range corridor needs with regard to through capacity, safety, structures, direct  connections, interchanges, ramp modifications, frontage road improvements, intersection improvements, and  parallel thoroughfares within the US 75 Corridor. The proposed project will analyze feasible and prudent transportation alternatives within the designated study area to evaluate a range of viable geometric alternatives (plus the No-Build), including integrating multiple alternative  transportation modes, technologies, alignments, toll-operated facilities, managed lanes, facility management, operations, capacity, affordability, and constructability. The development of mobility strategies will work to provide consistency with local, regional, state and national transportation goals and the development of strategies to fund and finance the project.
