NM 264 Alignment Study, Milepost 0 to 16

from the New Mexico/Arizona state line to the US 491 interchange near Yah-Ta-Hey in McKinley County

NMDOT Control No. 6101220

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 full depth reclamation of existing pavement, drainage improvements, and updating roadside barriers, signing and pavement markings.

The Study will document the existing conditions, identify traffic and safety areas of concern, investigate sensitive cultural and biological resources, seek public and agency feedback, identify improvement alternatives and arrive at a proposed improvement alternative.

Existing Conditions Identified:

  • Poor pavement conditions;
  • Roadway embankment erosion;
  • Right-of-Way limitations;
  • Lack of median drainage system;
  • Non-compliant pedestrian access routes; and
  • Significant sediment deposits.

Potential Improvements Include:

  • Improved roadside barriers;
  • Improved turnouts/access;
  • Updated pavement markings;
  • Upgraded ITS infrastructure (broadband);
  • Upgraded signage;
  • Addition of drainage improvements; and
  • Improved bicycle and pedestrian facilities.

The Context Sensitive Public Involvement Plan (CSPIP) is one layer of the Context Sensitive Solutions approach that NMDOT will use for the Study. The CSPIP is a living document that will evolve as the Study progresses and the team identifies concerns or issues. The public’s concerns and community values will be identified as stakeholders become involved in the process.

This CSPIP is based on the following guiding principles:

  • Provide continuous public access to study information as appropriate and opportunities for public input using a variety of outreach tools;
  • Identify the major community values and stakeholders and identify methods to inform and involve them, and the approaches to resolve issues, concerns and conflicts that may arise;
  • Link public involvement activities to study milestones, technical activities and decision-making;
  • Develop a decision-making process that involves the stakeholders in a meaningful way;
  • Document and maintain, in a central location, a record of all communication received throughout the Study;
  • Provide reasonable accommodations for those with special needs or those who are traditionally underserved to provide input into the overall process; and
  • Review the effectiveness of the CSPIP periodically to ensure that information is being disseminated efficiently and effectively.
