WBCM is providing services for the inspection and analysis of complex and electrified bridges for MDOT throughout the state. Representative projects include:

US 15 over the Potomac River: 14 span, 1,698-foot-long steel through truss. The inspection required coordination with CSX Railroad, National Park Service, and the use of rigging, flagging MOT, an under-bridge inspection vehicle, and a bucket truck.

MD 32 over Liberty Reservoir: 2 span, 579-foot-long deck truss. The inspection required the use of flagging MOT and an under-bridge inspection vehicle. Coordination with ongoing rehabilitation was required.

I68 Cumberland Viaduct: 43 span, 3,182-foot-long bridge of various span types and arrangements. The structure runs through downtown Cumberland, MD over Willis Creek, Western Maryland Scenic Railroad, CSX Railroad, United States Postal Service, city streets, and city parking lots. Multiple crews worked in tandem to complete the inspection. Manlifts and under bridge inspection vehicles were used for this inspection.

Electrified Inspections: Performed hands-on inspections of state-owned bridges with fracture critical members over Amtrak and the Washington Metropolitan Area Transit Authority during non-revenue hours. Coordination with the railroads was required for site access and for use of their inspection equipment.

Load Ratings: Performed load ratings based on as-built conditions for movable bridges, including rotating spans, single and double leaf, and bascule leaf bridges.
