Temporary works play a critical role in building major bridges, yet disappear once construction is complete. This article explores the TP3 temporary tower that supported the Pattullo Bridge end span for six months, enabling construction to proceed before the stay cables were engaged—and leaving no trace once its job was done.

The City of Port Moody has awarded Spannovation the design contract for the seismic retrofit and rehabilitation of the Barnet Highway Bridges over the CPKC rail corridor. Building on Spannovation’s prior seismic assessment, the project will advance through environmental review, geotechnical investigation, and detailed design—enhancing bridge resilience, safety, and emergency preparedness for the community.

The Sombrio Bridge (2012) replaced a timber span on Highway 14 with a two-lane steel plate girder crossing. Four girders, ~500t of steel, were launched without a nose or temporary pier. Stability was achieved using precast deck panels as counterweights, removed during tipping and added back as the cantilever grew. This construction-driven solution cut costs, improved safety, and strengthened the permanent bridge.
