N.M. Highway 264 (NM 264) is a 16-mile highway that extends west to east from the New Mexico/Arizona state line (Milepost [MP] 0) to the US 491 interchange near Yah-Ta-Hey (MP 16) in McKinley County. It serves as a key corridor to the Navajo Nation, connecting communities to Window Rock, AZ, located five miles across the Arizona border. NM 264 also connects to US 491 eight miles north of Gallup.

The New Mexico Department of Transportation (NMDOT), in coordination with the Federal Highway Administration, is conducting the NM 264 Alignment Study (Study) and identifying why improvements to this highway are needed. The purpose of the Study is to document existing conditions and develop highway improvement alternatives for the corridor.

The roadway improvements would be completed in segments as funding becomes available.

Funding for the Study includes state funds through House Bill 2-2021 Legislative Session (HB2-21).

Construction funding has been identified for a segment of NM 264 between MP 10 and MP 14 (Segment 1) under Control Number 6101221 and consists of state and federal dollars (e.g. HB2-21, Road Fund, STP Flex and STP Rural<5K).  Segment 1 highway improvements under consideration include reconstruction of the existing four lanes, drainage improvements, and updating roadside barriers, signing and pavement markings.
