Designing innovative structural solutions

Bridges and structures provide critical connections for our transportation system. Parametrix’s structural engineers develop solutions that balance technology and complex site considerations to reduce cost, construction time, and impacts to the human and natural environment. We help clients locate, survey, design, inspect, and maintain bridges, highway structures, and other unique structures.

Idaho Highway 16 Extension
Ada County, Idaho
Client: Idaho Transportation Department

The Highway 16 Extension provides a vital new north-south route near Boise and helps to improve transportation throughout the entire region. The new highway involved the design of three bridges, MSE retaining walls and several minor structures. Parametrix was the project manager for the whole project including a new 11-span, 1,730-foot-long-bridge over the Boise River designed by HNTB. Parametrix designed structures include an 88.5-foot-wide by 127-foot-long single-span prestressed girder bridge over Joplin Road and the Eureka Canal, and a 160-foot-wide by 36-foot-long single span buried prestressed slab bridge over Phyllis Canal.
