Getting from here to there.

For more than three decades, RETTEW has provided comprehensive bridge engineering services, from inspecting existing structures and designing new facilities to bridge elimination, developing fiscal bridge programs, and facilitating replacement solutions during emergencies — such as severe weather damage and flooding.

Our goal is to help clients maintain the safety of public structures, while keeping funding resources, long-term maintenance, and structural integrity in mind. And our philosophy is that we’re working with you, not for you.

RETTEW’s bridge and structure team looks at each project comprehensively. This big-picture, forward-thinking perspective allows us to find the right solution for a client’s needs, budget, and timeline. We’ve developed a niche reputation for context-sensitive solutions, integrating bridge designs into the surrounding natural details while maintaining historic integrity. And this doesn’t happen at a higher cost — we keep the materials and construction process as constructible as possible to benefit clients.

Efficient, fiscally responsible.

RETTEW’s bridge and structure experts are competent professionals who keep up with new technologies, industry best practices, and state and federal regulations. We’ve developed a reputation for going above and beyond — and for delivering projects ahead of schedule and under budget. Part of our secret is our solid relationships with contractors of all shapes and sizes, experienced with precast options, special solutions, historic structures, and large projects.

Recognized, reliable.

RETTEW has designed or rehabilitated hundreds of bridges and highways for state and county departments of transportation, turnpike commissions, county and local governments, and contractors. Our work has been continually recognized by professional organizations, including the American Society of Highway Engineers (ASHE), the Association for Bridge Construction and Design (ABCD), and the American Council of Engineering Companies (ACEC).
