The design of transportation facilities has been an integral part of our professional practice since our founding in 1949. Our experience includes straightforward local road widening and traffic calming measures, major freeway construction projects requiring state and federal agency approvals, multifaceted bridge crossings and support structures, and complex rail and light rail engineering.

Streets and Roadways

While the design of roadways may appear to be straightforward, it is the understanding, coordination, and planning of countless details that result in a functional, first-class project. We have experience in the entire process of improving roadways and traffic conditions, from conceptual planning and programming of projects, to preliminary and final design, including construction management. Our depth of experience provides invaluable insight by bringing construction issues into consideration early in the project. This allows for efficient project development (knowing the plans can and will be built).

Highways and Freeways

After years of limited funding and with traffic volumes far surpassing local capacity, freeway and highway projects are once again priority items. We not only engineer and build new facilities, much of our work is providing solutions to upgrade and improve existing systems.

Bridges

Nolte has been providing structural design services on diverse projects since the mid '50s. Our structural teams' credit includes major highway, roadway, railroad/transit, and bridge structures, as well as small stream and river crossings. We have designed hundreds of these structures, some as complex as drawbridges and freeway interchanges, others as simple as sound walls, retaining walls, and drainage culverts.
