Scope of Work:

Buckland & Taylor Ltd. prepared the demolition engineering plan for the Contractor for the US Grant suspension bridge. Buckland & Taylor Ltd. analyzed the capacity of the bridge to ensure it could safely support its own weight and wind loading during all stages of demolition. The bridge deck and trusses were cut at pre-determined locations into 11 m (35 ft.) long pieces and removed following a predetermined sequence using a barge mounted crane. Once the trusses and deck were removed, the main cables were cut using explosives, dropping the towers and cables into the river clear of the navigation channel for subsequent removal.

Completed in 2001.
