CDM Smith delivers bridge and structural engineering services that strengthen connectivity, improve safety, and support long-term infrastructure resilience. Our teams design highway, interchange, and pedestrian bridges for complex operating environments—balancing structural performance, constructability, cost, and aesthetics. We apply rigorous engineering analysis alongside value engineering, independent Category III checks, and structural assessments to ensure durability and compliance. From concept development through detailed design and construction support, we provide coordinated solutions that manage risk, extend asset life, and deliver dependable connections across transportation networks.

Highway and interchange bridges

We design highway and interchange bridges that support high traffic volumes and complex geometries. Our teams address structural performance, durability, and integration with surrounding infrastructure and corridors.

Pedestrian and multimodal bridges

CDM Smith delivers pedestrian and cyclist bridge designs that enhance safety, accessibility, and user experience. Designs consider accessibility, urban context, and architectural quality while meeting operational and maintenance requirements.

Constructability, durability and lifecycle design

Our bridge designs account for construction sequencing, staging, and long-term maintenance. This lifecycle-focused approach improves buildability, reduces risk, and extends asset service life.

Integrated design and delivery support

We support bridge projects from concept and preliminary design through detailed design, tender documentation, and construction support—working closely with stakeholders to manage interfaces, constraints, and approvals.
