Project Overview

The New Mexico Department of Transportation (NMDOT) in cooperation with the Federal Highway Administration (FHWA), is planning to replace the east- and west-bound bridges on N.M. Highway 500 (Rio Bravo Boulevard) spanning the Rio Grande in Albuquerque within Bernalillo County.  The Project Area is located between N.M. Highway 314 (Isleta Boulevard SW) and N.M. Highway 303 (2nd Street SW), and includes the two bridges crossing the Rio Grande and the Middle Rio Grande Conservancy District (MRGCD) Albuquerque Riverside Drain. Rio Bravo Boulevard is a critical east-west route in Albuquerque’s South Valley and is one of seven Rio Grande crossings in the Albuquerque metro area.

The purpose and need for this project is to address structural deficiencies while also reducing congestion and improving multi-modal transportation system connectivity within the project limits.  The needs are based on the fact that the eastbound river bridge is in poor condition and requires replacement, pedestrian and bicycle facilities are discontinuous in the project limits, and it has been determined that additional river crossing capacity is needed in the metro area.

Previous Public Involvement

Public involvement began in 2020 during the development of the Phase A/B Study.  This section of Rio Bravo Boulevard serves a broad and diverse set of stakeholders including tribal governments, federal and state resource agencies; county and local agencies; community residents; commuters; area businesses; elected officials; and other users of the bridge within the Albuquerque Metro area.  Due to the COVID-19 pandemic, in-person community and stakeholder engagement was not feasible for the Phase A/B Study efforts, which necessitated the development of a virtual engagement strategy to reach a wide audience and seek effective tools for public participation.

Coordination with stakeholder agencies was conducted via email, telephone, and virtual meetings. A virtual public meeting was hosted on Wednesday, December 9, 2020 (see link to recorded meeting below) using Zoom, a web-based service with call-in capabilities.  A web link offered access to meeting registration, the NMDOT Projects webpage, and a MetroQuest Survey option during the comment period. 

124 People Attended the 2020 Public Meeting

524 Comments were Received

Priorities Identified during Phase A/B Public Involvement
  1. Safety
  2. Environmental Impacts
  3. Long-Term Vehicle Capacity
  4. Improved Facilities
  5. Construction Duration

Common concerns centered around noise from traffic and trucks along the corridor impacts from construction traffic through local neighborhoods, drainage and flooding concerns, Dean Road and Rio Bravo Blvd intersection safety, impacts on properties, the safety of the nearby properties and crime, pedestrian and bicycle access, and continued notifications of public meetings and project updates to the local property owners.

Input was gathered to identify issues of interest and concern and to develop, evaluate, and refine project alternatives. A preferred alternative was then identified and the Phase A/B Study was completed in September 2021. The Study and project-related information can be found in the PROJECT RESOURCES below.

What is Planned for this Project?

The preferred alternative in design development involves the replacement of the Rio Grande Bridge with a 14-span, steel girder bridge. A 2-span, pre-stressed concrete slab girder bridge and a continuous, closed pipe culvert would replace the bridge over the Albuquerque Riverside Drain. The open portion of the drain would have a continuous culvert pipe that crosses under Poco Loco Drive, the Rio Bravo Bridge, and Dean Road. In addition to this, retaining walls and pedestrian access elements are under development.


We invite you to join the public meeting, to learn more about the project design underway, and ask questions.

Below are 3-dimensional (3D) photo simulations prepared to illustrate how the proposed bridge improvements would fit within the Rio Bravo Boulevard corridor.  These simulations highlight the preferred design alternative (Alternative 6), which is a straight partially offset alignment to the north of the existing alignment.  This alternative has an increased profile and longer bridge spans.  This preferred design alternative would include pedestrian safety improvements, address key deficiencies to the existing bridge structures, and would be designed with the capacity to add an additional lane of traffic in each direction at an undetermined date in the future.
