Bridges
Bridges are gateways to commerce and opportunity, connecting people and bringing communities large and small together. We’ve helped build these links for more than a century. We provide engineering, design and construction management services for new bridges and bridge replacement projects nationwide.
Our bridge engineers design to the selected criteria utilizing AASHTO Load and Resistance Factor Design (LRFD) or other applicable AASHTO methods. Our geotechnical and hydraulics teams see that your project rests on a solid foundation.
Beyond Bridge Functionality
Our team has the necessary in-house experience to help meet your project’s state and federal requirements, prioritize safety and efficiency, and reflect the culture of your community. We have specialists in environmental permitting, planning, comprehensive design, right-of-way acquisition, risk assessment, construction, construction management, safety and public engagement.
Bridges influence the movement and life of your community, so we are focused on how people move over them and adapt to new technologies, from autonomous vehicles to ride-sharing services to bike and pedestrian corridors. Our priority is to continually improve the safe and efficient movement of people and goods in, out and through population centers.
Aesthetics, often critical to successful bridge design, allow a structure to fit with its surrounding environment. Our bridge designers specialize in incorporating historic, ornate or modern elements while remaining within the scope.
Wide-Ranging Experience With Bridge Projects
We have designed, constructed and updated bridge structures of all types, from short-span highway overpasses to long-span major river crossings for highway, railway and pedestrian facilities. We can deliver complex fixed and movable bridge projects using conventional or accelerated construction techniques through a variety of design-bid-build, design-build or progressive design-build contracting methods.
Our team also brings experience with culverts, retaining walls and sound walls, as well as the temporary structures needed to handle traffic during demolition or construction. We complete traffic studies, hydraulic studies, seismic analyses and vessel collision studies.
