PROJECT HIGHL IGHTS 2022•2023

5 TH STREET BRIDGE REPAIRS The 5 th Street Bridge is a vital component of the City of Courtenay’s infrastructure and an important local landmark. Nearing the end of its service life, rehabilitation was required. In consultation with the City, it was apparent that a full closure of the bridge was not feasible. A complex 40-year service-life extension was completed by the multidisciplinary team of Thurber (materials: concrete topping, cathodic protection system, coatings, contract administration), Hatch (structural), PBX (electrical), lead by Urban Systems (prime consultant, environmental and traffic design). The rehabilitation involved complex traffic and environmental management, lead coating abatement, structural steel repairs, concrete deck repair, installation of a high-performance concrete overlay with an integral impressed current cathodic protection system (ICCP)—all while maintaining single-lane alternating traffic. Participants: Thurber: Mark Byram, P.Eng., Oleksandr Lisoivan, P.Eng.; Urban Systems: Eric Sears, P.Eng., Natasha Elliott, P.Eng.; Hatch: Filip Hristov, P.Eng., Samson Lee, P.Eng.; PBX: Irvin Naidu, P.Eng.; City of Courtenay: Chris Davidson, P.Eng.
