Bridge Engineering


"Our diverse and extensive expertise allows us to consistently deliver innovative yet practical solutions to bridges of all sizes, construction, and vintage."

— Brian Santosuosso, Associate Principal and Unit Manager

Bridge structures are subject to harsh conditions and require ongoing maintenance and rehabilitation to achieve long-term performance. Through the investigation of thousands of bridges and notable bridge failures, WJE bridge engineers have learned that improved bridge rehabilitation designs are accomplished through a better understanding of the problems. WJE’s knowledge of bridge performance is supported by technical expertise in structural engineering, materials, laboratory and field testing, and instrumentation.

WJE bridge engineers have extensive experience conducting field investigations of bridge deck, superstructure, and substructure problems involving a wide range of bridge materials and structure types. Supported by extensive laboratory facilities, nondestructive testing capabilities, and in-house expertise in WJE’s Janney Technical Center, WJE professionals are routinely called upon to complete fatigue and fracture investigations, corrosion assessments, and collapse investigations.
