IRONWORKERS MEMORIAL SECOND NARROWS CROSSING The Ironworkers Memorial Second Narrows Crossing (also known as the Ironworkers Memorial Bridge) connects the two shores of the Burrard Inlet in Vancouver. At over 60 years old, weighing 20,000 tons, and facilitating 125,000 trips per day, it was crucial to assess the bridge’s condition. Partnering with Associated Engineering (AE), Thurber Engineering Ltd. has been involved in the assessment of the bridge since 2021. Over this time, the team has conducted coating condition assessments for recoating the bridge beams, utilized drones to map surface delamination, performed continuous corrosion potential measurements of reinforced steel using a wheeled electrode, and used ground penetrating radar to estimate concrete thickness and identify faults. Thurber has supported AE in developing rehabilitation options throughout the project to sustainably extend the service life of this crucial infrastructure. Company: Thurber Engineering Ltd.
