I-25 Nogal Canyon Bridge Replacement Project

The New Mexico Department of Transportation (NMDOT), in coordination with the Federal Highway Administration (FHWA), is replacing the Interstate 25 (I-25) truss bridges over Nogal Canyon at Milepost 107 in Socorro County with two new structures. The new structures and surrounding roadway will be updated to meet current safety and performance standards. The new three-span steel structure and roadway improvements will enhance safety, stability, and long-term reliability along this section of I-25.

• IMPROVE safety for drivers and freight traffic.
• PROTECT the environment by reducing erosion and enhancing slope stability.
• ENSURE long-term reliability of New Mexico’s interstate network.
• MAINTAIN regional connectivity for residents, tourists and commercial freight.

Built in 1968, the Nogal Canyon bridges are located on I-25 in between Socorro and Truth or Consequences, New Mexico.

The bridges are three-span Warren Truss structures with a 265-foot main span and a total width of 34 feet (two 12-foot lanes with narrow shoulders). They sit within an I-25 right-of-way that ranges from about 200 to 550 feet wide, surrounded by lands owned by the Bureau of Land Management, the State of New Mexico, and private property owners.

• Realignment and widening of I-25 through Nogal Canyon
• Drainage improvements to the existing slopes and canyon
• Slope stability improvements including erosion improvements
• New signing and striping to enhance visibility and safety
