US-75 From County Line Rd. to FM1417 – TxDOT Paris District


About this Project

EST provided design services for this project, the purpose of which is to widen US 75 from a 4-lane rural to 6-lane divided rural freeway from the Collin County Line to FM 1417 in Grayson County (14-miles). Convert frontage roads from 2-way to 1-way operation, add two new location interchanges (Hall Cemetery Rd & Spence Rd/FM 121 New Location), and widen bridges/add retaining walls associated with the capacity improvements.

The EST team performed:

  • Prepare the Project Schematic and Environmental Document,
  • Conduct Public Involvement including Public Meetings, Public Hearings, and Meetings with Affected Property Owners (MAPOs), and Stakeholder engagement,
  • Obtain NEPA Clearance and related Permits,
  • Obtain Executed Railroad Agreements,
  • Prepare ROW Exhibits (New I/C Locations Only),
  • Perform Survey, Geotechnical Sampling and Testing, Subsurface Utility Engineering (SUE), and Utility Coordination,
  • Prepare Plans, Specifications, & Estimates (PS&E) packages, and
  • Support construction operations.

Key Challenges: Operational ROW. No new right-of-way except at new interchange locations.

Key Challenges: Union Pacific Railroad Coordination. Reconstruct two bridges spanning UPRR facility south of Sherman, TX.

Key Challenges: Project Phasing. Project delivery will support separate PS&E deliveries based on funding availability.

Key Challenges: Frontage Road Conversion. Maintain access from the service roads to cross streets, residential, and commercial properties.

Key Challenges: Adjacent Projects. Coordinate ultimate design with FM New Location Projects (FM 121 and FM 902).
