Bridges are more than passages over water; they are landmarks in their own right that support the flow of people and goods. Bridges touch people every day, providing critical access channels as well as visual context.  Communities and owners typically require structures whose appearance enhances the surrounding area while reducing congestion and promoting neighborhood revitalization.

WSP USA, formerly WSP | Parsons Brinckerhoff, has worked on thousands of structures that have become hallmarks of the communities they serve.  Our staff is well versed in steel and concrete bridges, including cable-stayed, arch, truss, segmental, suspension, girder, movable and floating, as well as multi-level highway interchanges.  For highways, railroads, transit systems and pedestrians, our bridge services range from feasibility studies and environmental permitting through preliminary and final design, to program and construction management.  We also provide inspection, rating, seismic analysis, rehabilitation design, and value engineering services.

Balancing technically challenging designs with complex site considerations, our projects have won numerous prestigious awards for engineering excellence.  As a measure of our efforts, we are proud to have been selected as the Top Bridge Design Firm (#1) for 2017 in a recent survey published by Roads and Bridges magazine.

Our bridge assignments range in size and scope from simple studies and assessments to complex multibillion-dollar multidisciplinary efforts involving landmark structures.  No matter how big or small the job, WSP is committed to maximizing infrastructure resources and responding to today's needs with cost-effective, aesthetic solutions.
