Bridges & Structures

For more than 60 years, HDR has designed bridges and structures that are unique to each client's needs. We don't subscribe to a certain aesthetic style or even type of structure, but listen to the client and determine what is best for each situation and each community. Over the years, we have engineered a wide range of bridge types from long span, arch, truss and cable-stayed to medium- and short-span girder, curved girder and box girder. Our experience encompasses historic structures and movable ones, major river crossings and directional freeway interchanges. In addition to highway structures, we also offer planning, design and construction services for structures at airports, on rail lines and for transit systems. On every project, we employ progressive design and construction techniques with sensitivity to function, environment, aesthetics and cost.
