The New Mexico Department of Transportation (NMDOT) is initiating the Interstate 25 (I-25) / Missouri Bridge Replacement Study to develop and evaluate alternatives for replacing Missouri Bridge at I-25 in Las Cruces. The goal of the study is to develop and evaluate alternatives that would improve the structure, improve sight distance on southbound I-25, and improve safety conditions. We will look at possibly widening I-25 with additional travel lanes based on existing and future traffic forecasts. We will propose a new bridge to allow Missouri Avenue sufficient room to expand into the future.


Comments: Will be accepted by Hilary Brinegar, Marron and Associates, 3655 Research Drive, Genesis Center- Bldg C, Las Cruces, N2 Mexico 88003-8001, by phone at (575) 618-7351, or by email hbrinegar@marroninc.com .

I-10/Avenida de Mesilla Interchange

The project will consist of replacing the steel girder bridges with a concrete bridge with full height abutments, precast concrete deck panels and artwork featuring a local southwest theme. The ramps will be reconfigured to a diamond interchange with the removal of the existing loop ramps, which will provide a longer acceleration lane on I-10. In addition, there will be signalization installed at Avenida de Mesilla and the eastbound entrance and exit ramps. The project will incorporate ADA improvements to Avenida de Mesilla from Hickory Loop to Lakeside Drive, which includes utility upgrades to the gas; sewer, water lines, and landscape planting.
    All ramps remain open with minor work along I-10 with traffic reduced to one lane. Alll lane restrictions have been lifted on Avenida de Mesilla.

US 70 Wildlife Crossing Study
The New Mexico Department of Transportation is conducting a Wildlife Crossing Feasibility Study for eight miles of US Highway 70 (US 70) in the San Augustine Pass area from milepost (MP) 162 to MP 170. The purpose of the study is to gain an understanding of wildlife movement through the study area, and to develop ways to facilitate wildlife movement while reducing the potential for animal‐vehicle collisions.

I-10/Mesquite & Vado Interchange
Las Cruces, NM

The New Mexico Department of Transportation (NMDOT) with El Terrerro Construction will be reconstructing the I-10 Mesquite Bridge, along with realigning the ramps. Once this portion of the project is complete, the contractor will move over to the I-10 Vado exit where 2 round abouts will be constructed at each end. Both interchanges will have lighting enhancements place at the bridge and ramps.

CURRENTLY: The contractor has placed traffic control along Interstate 10 that will affect east and westbound traffic. The eastbound lanes have been switched to the westbound lanes and traffic is now restricted to one lane for both directions at the Mesquite exit. The Mesquite bridge overpass is now closed and will remain CLOSED for approximately 6 months as demolition and reconstruction is on-going.  The Mesquite on and off ramps are currently CLOSED and will be opened once ramps are reconstructed. ALL other ramps at Vado exit 155 remain open to residents and business, along with full access on the frontage roads.

Motorists are encouraged to reduce speed and to proceed with caution during peak hours. Should an incident occur within the restricted in which the concrete wall barrier is located, and is considered non-life threatening, law enforcement is requesting that drivers move their vehicles over to a safe location so that they can assist and assess the situation. This will allow the flow of traffic to continue safely.

NM 90/Hudson Street Replacement Project
Silver City, New Mexico

CN 1100560

The New Mexico Department of Transportation (NMDOT) is developing plans for the replacement of the NM 90/Hudson Street Bridge in Silver City. The existing bridge would be demolished, and a new bridge would be constructed over the San Vicente Arroyo to the south of Broadway. The new bridge would be wider than the existing bridge and include sidewalk(s) and bike lane(s). Lighting would be upgraded, and signs would be placed. During bridge construction, a temporary detour route would be established, and various options for routing this detour to the west of NM 90 are being considered. As part of this project, additional turn lanes would be constructed at the US 180/County Bypass Road intersection. Environment, geotechnical, and utility investigations will be conducted for this project.

U.S. Highway 70/N. Main Street

Scope: The contractor will be installing new utility lines, reconstruction roadway, upgrade sidewalks with ADA improvements, curb and gutter, and new traffic signalization. Motorists will encounter lane restrictions with a 10 foot width allowance from mile post 148.3 to 149.2. Motorists are urged to seek an alternate route during peak hours and make adjustments for delays.

Currently The NMDOT and the Contractor have placed traffic control devices along the work zone with lane restictions of 10 feet. Work is on-going with new utility lines being placed within the median and inner lanes. All access and businesses are open, please contact the local businesses for their hours of operation. Please proceed with caution, as pedestrians are present within this area.

Cambray Bridge Replacement
NM-549/Union Pacific Railroad Crossing

These environmental documents are part of the Environmental Assessment (EA) evaluations that consist of the replacement of the existing Cambray railroad overpass on NM 549 and associated improvements to the adjacent roadway in Luna County, New Mexico. Improvements to the roadway are proposed by the New Mexico Department of Transportation (NMDOT) and the Federal Highway Administration (FHWA). The Cambray Bridge Improvements EA was developed in accordance with the National Environmental Policy Act (NEPA) of 1969, the Code of Federal Regulations (Title 23 CFR Part 771), and the NMDOT Location Study Procedures (NMDOT, 2000a). The purpose of proposed improvements is to address existing deficiencies, improve safety, and to insure the future viability of the NM 549/Union Pacific Railroad crossing in providing for the safe and efficient movement of vehicular and train traffic within the project area.
