Preserving a Well-loved Heritage Structure

One of Metro Vancouver’s oldest, most interesting and historic structures, the Westham Island Bridge is the single gateway onto Westham Island in Delta, BC, which is home to key agricultural developments, a sports club, and popular local tourist attractions. Now entering its 106th year, the Westham Island Bridge needs a comprehensive structural assessment and rehabilitation study that will consider extending the structure’s life for another 20 to 25 years such that it can continue to provide safe and reliable access to the island. Mott MacDonald has been retained by the Owner to undertake this asset preservation work in three phases comprising a comprehensive structural assessment and rehabilitation plan, detailed design of the rehabilitation works and construction support. This paper describes the recent work undertaken in Phase 1 to formulate a cost effective rehabilitation strategy for the bridge.
