Bridge Design & Engineering

Constructability and structural integrity are hallmarks of Erdman Anthony’s bridge design tradition. Our firm turns effective analysis, innovative design, and construction management into lasting landmarks in transportation infrastructure and provides solutions for state DOTs, toll road authorities, and municipalities throughout the eastern United States.

Our approach begins with meticulous study of every facet of your project, including overall objectives, schedule requirements, budget constraints, community impacts, and environmental sensitivities.

It takes a lot of experience and know-how to navigate the federal and state regulatory approval processes smoothly. Erdman Anthony has close working relationships with the permitting agencies in the states where we work regularly.

Trust Erdman Anthony to bring these relationships to your bridge project.
