When the needs of all stakeholders are incorporated into a bridge design, the result is a well-balanced, constructible solution. DEA’s bridge engineers take a bird’s eye view of site opportunities and constraints, community concerns, and design and construction issues before beginning the design process. The results are sustainable bridge designs that are tailored to the communities they serve.
