Making a positive impact on the sustainability and safety of the communities where we work and live.
Souder, Miller & Associates (SMA) transportation design services are recognized throughout New Mexico by our clients: NMDOT personnel, New Mexico local governments and tribal officials. SMA has been called upon to design both large and small projects: small projects to provide quick response, design solutions and construction plans for traffic signalized intersections; large projects to provide thorough evaluation of all design alternatives, context sensitive solutions to cultural resources, biological conditions, public involvement and cost-effective construction engineering solutions.
SMA, focusing on our commitment to quality and service, conducts location and feasibility studies for the upgrading of existing highways and interchanges as well as design of completely new transportation facilities. Recent design experience includes State and Interstate highways, rural and urban arterial and collector streets, and signalized intersections. In addition, SMA can provide alignment alternative analysis, utility extension design/utility coordination, right-of-way maps, historical/cultural/biological reports, curb and gutter design, public information meetings, sidewalk/ bicycle path design, landscape design coordination, structural design, parking lot and driveway design and public information meetings, as well as surveying and stormwater drainage analysis and design.
I-25 / Engler Grade Separation Project
SMA successfully completed this project through the cooperative efforts between local agencies, NMDOT, FHWA, and all major stakeholders involved in the planning, design and construction of this venture.
I-40 / US 285 Clines Corners Interchange
SMA completed an alignment study with preliminary and final engineering design for this major north/south transportation route in the state, which also connects I-25 and I-40.
7th Street and Sligo Street Roads and Bridge
SMA completed the design and construction support services for this road extension, connection and bridge project in Cortez, CO. The bridge’s retaining wall was the largest Redirock structure in the U.S. at the time.
