what we do

Roadway and Highway Design

Designing infrastructure to safely and efficiently move people and goods

Providing safe and efficient roads and highways is more challenging today due to limited funding and increasingly complex regulatory processes. Parametrix works with clients to develop solutions that are cost effective and minimize disruption to users and the environment. We incorporate LID, green streets, and complete streets principles to create appealing, safe, and sustainable transportation right-of-ways.

NM 159 Drainage and Roadway Reconstruction 
Mogollon, NM
Client: NMDOT

NM-159 and associated drainage structures were heavily damaged, and in most areas completely washed out, following a major flood in September 2013. As a result, access to the historic mining town of Mogollon and the surrounding Gila National Forest was severely limited. This project to restore 2 miles of highway, providing safe, permanent access for residents and tourists, received FHWA Emergency Relief funding. This required that all design and permits and approvals had to be completed and obtained within 9 months. Parametrix was the lead designer and environmental consultant for the project involving several bridges, culverts, and water crossings. The surrounding historic district, archaeological sites, and complex array of private property ownership created challenges for the design. The project involved extensive public involvement activities, where the team developed and implemented a public involvement plan to engage the area’s 54 property owners in the design and environmental process.
