U.S. Highway 180 Corridor Safety Scoping Project

West of Silver City to East of Santa Clara (Milepost 111 to Milepost 123)
Control Number 1102290

PROJECT OVERVIEW

U.S. Highway 180 (US 180) is an important east–west route that runs from central Arizona through southern New Mexico and into northern Texas. In southwestern New Mexico, it connects the communities of Silver City, Bayard, and Hurley, and links to major highways such as I-40, NM 26, and NM 90.

The project corridor covers about 11 miles, from just south of Bayard (milepost 123) to just west of Silver City (milepost 111, see Figures 1 and 2). This section is mostly a divided, four-lane roadway, with speed limits ranging from 55 mph in rural areas to 35 mph in town centers. The corridor includes residential neighborhoods, commercial zones, and open spaces, serving local traffic as well as pedestrians and cyclists traveling to nearby schools, Western New Mexico University, sports facilities, and trails.

US 180 also plays a role in community events like the Tour of the Gila, a major cycling race that uses parts of this corridor and NM 90. Wildlife safety is another important concern—this section has been identified as New Mexico’s second-highest priority area for reducing wildlife–vehicle collisions (NMDOT, 2022).

Safety challenges along the corridor include vehicle crashes, wildlife conflicts, and limited infrastructure for pedestrians and bicyclists. The safety scoping effort aims to identify improvements that will reduce crashes, improve safety for all users, and enhance emergency response times. By addressing these issues, the project will help create a safer, healthier, and more connected corridor for everyone who lives, works, and travels in the area.

Where are we in the Project Development Process?

Currently in the planning phase, this project is part of NMDOT’s Target Zero initiative, which aims to eliminate traffic fatalities and serious injuries on New Mexico’s roads. It is supported by federal funding from the Highway Safety Improvement Program (HSIP), ensuring that safety remains the top priority throughout the process.

The project team is currently collecting data on existing conditions along the corridor. This fall and winter, the team will share findings with the community to gather feedback and help refine potential improvement options. Once public input is incorporated and the alternatives are analyzed, a prioritization plan will be developed to guide phased implementation as funding becomes available.

The New Mexico Department of Transportation (NMDOT) will hold an open house to share information about the US 180 Corridor Safety Scoping Project, which includes the segment of US 180 between milepost 111 west of Silver City and milepost 123 in Bayard. The project is examining safety issues affecting motorists, bicyclists, and pedestrians within the corridor as well as potential solutions to improve traffic operations and reduce hazards. At the open house, NMDOT will present findings from reviews of current road and intersection conditions, highlighting potential hazards and recommended improvements. Community members and US 180 users from Silver City, Rosedale, Arenas Valley, Santa Clara, and Bayard are invited to provide input, ask questions, and share safety concerns.

Please send any initial comments by January 12, 2026 to the following email or on the project website:

Public Engagement Approach

The public engagement process for this project is designed to give community members and stakeholders meaningful opportunities to share input on all aspects of the scoping project. Feedback will help identify key safety issues along the corridor—especially for pedestrians and bicyclists—while also shaping the project’s goals, priorities, and potential solutions.

A unique aspect of this effort is its two-phase approach. The first phase focuses on the area in Silver City, where safety needs are most urgent, particularly for people walking and biking. At the same time, outreach will consider the broader US 180 corridor, ensuring that local discussions connect to the larger vision for the entire route. As the study progresses, future outreach will continue to include communities throughout the corridor, helping guide improvements that reflect the needs and experiences of everyone who uses US 180.
