Ultrasonic pin inspection experts from bridge engineering firm Modjeski and Masters will be implementing an advanced inspection technique to “see” inside critical steel pins on the eastbound span of Maryland’s Chesapeake Bay Bridge.

Bridge engineering firm Modjeski and Masters is currently inspecting the 3,200-ft. eastbound span of Maryland’s Chesapeake Bay Bridge as part of a joint venture with RK&K Engineers. The Modjeski and Masters team will be inspecting part of the floor system, superstructure, railing anchor bolts, roadway deck, light poles and steel truss structural members.
Ultrasonic pin inspection experts from Modjeski and Masters will be implementing an advanced inspection technique to “see” inside critical steel pins. Ultrasonic testing (UT) technology will enable the team to evaluate structural integrity and conditions of bridge components that are not visible, aiding in the identification of irregularities within the structure. It is expected that the team will shoot approximately 15 pins throughout the duration of the inspection.
The Chesapeake Bay Bridge is a vital traffic link that connects the Baltimore-Washington Metropolitan Area with eastern shore cities, including Ocean City, Md. The bridge also serves as an alternate route for I-95 between northern Delaware and Washington, D.C. Because it is such a heavily traveled route, maintaining bridge traffic throughout the inspection is critical. Inspection teams will leverage access vehicles to minimize travel disruptions. Bridge traffic will remain open throughout the duration of the inspection, with one of the bridge’s two eastbound travel lanes closed through portions of the inspection.
