Notice of Intent to Prepare an Environmental Impact Statement for Spur 399 Extension, Collin County

Collin County, Texas -- 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 the Spur 399 Extension, an eight-lane freeway on new location connecting United States Highway (US) 75 south of McKinney to US 380 north of McKinney, in Collin County, Texas.

In April 2020, TxDOT completed the US 380 Feasibility Study for Collin County, which recommended an alignment for the Spur 399 Extension between US 75 and US 380. One of the alternatives under consideration was part of the recommended alignment from the US 380 Feasibility Study. The EIS will evaluate a range of build alternatives on new location and a no-build alternative. Possible build alternatives are located to the east and west of the McKinney National Airport.

TxDOT anticipates completing the study process for this proposed action by Jan. 2023.

The public is requested to identify in writing potential alternatives, information, and analyses relevant to this proposed project. Such information must be received by Mar. 10, 2021.

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 Dec. 9, 2019, and executed by the Federal Highway Administration and TxDOT.
