Bridges & Structures

Designing Connections. Strengthening Communities.

Whether it is a traditional bridge, signature structure or historic landmark, every project brings a unique combination of technical, operational, financial and community considerations. 

For more than eight decades, we have partnered with clients to plan, design, deliver and maintain bridges and structures of every type and scale, enabling connections for generations to come. Through a network of more than 40 bridges and structures technology centers, specialists from multiple disciplines and geographies collaborate to share expertise, advance innovation and help clients solve increasingly complex infrastructure challenges to enhance mobility and quality of life.

Listening First. Delivering What Matters.

The best solutions begin with listening and understanding the unique needs of each client and community. We navigate complexity by leveraging decades of engineering innovation and experience with new technologies to uncover solutions that deliver the most value. Our technical capabilities include all types of bridges, from major river crossings, complex structures and highway caps to rail systems, movable bridges and historic rehabilitations. The result is resilient, context-sensitive solutions that balance performance, constructability, community priorities and long-term stewardship with a focus on safety, quality and lasting value.

Increasing Bridge Safety, Strength and Longevity

As bridge inventories age, funding pressures increase, inspection requirements change and performance management challenges grow, infrastructure owners need strategies that extend asset performance and lengthen service life. We support every stage of a structure's life cycle, bringing together planners, engineers, inspectors and construction professionals to evaluate options and manage risk. 

Going beyond engineering and technical expertise, we leverage our funding, communications, stakeholder engagement, environmental planning and real estate specialists to successfully advance projects that will reliably serve communities today and into the future.
