Bridge and structural engineering form the foundation of ERA’s consulting services. The primary focus of our structural team is to ensure safe travel over grade separations and waterways. Working together with our roadway and hydraulic teams, we design a variety of structures including multi-span bridges, single-span bridges, culverts, and retaining walls. Our team is known for its responsiveness to clients, creative problem-solving skills and extensive experience with the federal process.
