Notice of Intent to Prepare an Environmental Impact Statement - US 380, Collin County


Pursuant to 23 C.F.R. §771.123(a), FHWA, on behalf of TxDOT, is issuing this notice to advise the public that an Environmental Impact Statement (EIS) will be prepared for a proposed transportation project to construct an eight-lane freeway along the US 380 corridor from Coit Road in Prosper (west of McKinney) to FM 1827 (east of McKinney), in Collin County, Texas.


In April 2020, TxDOT completed the US 380 Feasibility Study for Collin County, which recommended an alignment for an improved US 380 across Collin County. The Coit Road to FM 1827 section of the Recommended Alignment from the Feasibility Study is the basis for development of the alternatives to be considered in the EIS. The EIS will evaluate a range of build alternatives and a no-build alternative. Possible build alternatives include improvement of the existing US 380 alignment, the Recommended Alignment between Coit Road and FM 1827 from the 2020 US 380 Feasibility Study, and three additional new location alternatives that consider optional alignments through the Town of Prosper within the western portion of the project area and along the East Fork of the Trinity River within the eastern portion of the project area.

TxDOT anticipates completing the study process for this proposed action by December 2022.

The public is requested to identify in writing potential alternatives, information, and analyses relevant to this proposed project. Such information must be received by February 5, 2021.

Memorandum of Understanding:

The environmental review, consultation, and other actions required by applicable Federal environmental laws for this project are being, or have been, carried-out by TxDOT pursuant to 23 U.S.C. 327 and a Memorandum of Understanding dated December 9, 2019, and executed by the Federal Highway Administration and TxDOT.
