NM 14, NM 536, and Frost Road Intersection Reconstruction

Between Milepost 5.73 and Milepost 6.13, San Antonito, NM
NMDOT Control No. A301442

Project Overview

The NMDOT, in cooperation with the Federal Highway Administration, is proposing improvements to the intersection of NM Highway 14 (NM 14), NM Highway 536 (NM 536), and Frost Road in Bernalillo County, New Mexico. These three roadways are significant thoroughfares in the East Mountain region and the intersection provides interconnectivity to numerous local communities including Cedar Crest, San Antonito, Sandia Park, and Tijeras as well as recreational access to lands managed by the U.S. Forest Service. NM 14 runs north-south connecting Santa Fe to Albuquerque and also known as the Turquoise Trail, a National Scenic Byway.  The current project involves the design and construction of a roundabout that will replace the existing intersection and will keep traffic flowing from all directions.

In 2017 and 2018, the NMDOT conducted a Phase 1-A/B Study (Study) for NM 14 from Interstate 40 (milepost 0.0) to NM 536/Frost Road (milepost 6.1) under Control Number A301440.   The purpose of the Study was to improve driver expectation, improve access spacing, and consider multi-modal opportunities. During the Study Phase, the intersection was analyzed and design alternatives were developed.  The Study found that the roundabout alternative analyzed ranked the highest in terms of meeting the evaluation criteria and with public input was chosen as the preferred alternative.

Public Involvement

Previous Public Involvement

During the Phase 1-A/B Study phase, a public meeting was hosted on July 18, 2017 at the Vista Grande Community Center and a series of coordination meetings were held with Bernalillo County and the Greater Albuquerque Bicycling Advisory Committee.  A preferred alternative was identified and the Phase 1-A/B Study was completed in April 2018. The Study and project related information can be found in the PROJECT RESOURCES below.  Due to funding limitations, projects identified in the Study were implemented in phases within the NM 14 corridor as funding became available.

Phase 1, I-40 to Casa Loma Road (NM 14 Milepost 0 to 2)
Pavement Rehabilitation: Completed 2018

Phase 2, Casa Loma Road to Melcor de Canoncito Road (NM 14 Milepost 2 to 4)
Pavement Rehabilitation: Completed 2019

Phase 3, Melcor de Canoncito Road to Frost Road (NM 14 Milepost 4 to 6)
Pavement Rehabilitation: Completed 2020


Phase 4, Slope Erosion Mitigation (NM 14 Milepost 3.5 to 4.2)
Funding Programmed in 2022/2023

Phase 5, NM 14/NM 536/Frost Road Intersection Improvements (NM 14 Milepost 5.5 to 6.1)
CURRENT PROJECT with Funding Programmed in 2023/2024

What is Planned for this Project?

The current project (Phase 5) will entail reconstruction of the NM 14, NM 536, and Frost Road intersection. The roundabout will include green stormwater infrastructure, addition of multi-modal facilities, and continuous traffic flow.  Construction is anticipated to start in late 2023 or early 2024.
