Spencer Bridge Engineering has completed factory testing on a bespoke access system designed for the Pattullo Bridge Replacement Project in British Columbia, Canada. The system, developed by the company’s in-house team, will be used to inspect and maintain the bridge’s stay cables.
Following successful testing in the UK, witnessed by representatives from Fraser Crossing Constructors General Partners (a joint venture between Acciona and Aecon) and an independent checker, the equipment is now being shipped to Canada for installation and commissioning.
The Pattullo Bridge, which spans the Fraser River near Vancouver, is being replaced to meet modern safety standards and improve connections between Surrey and New Westminster. Spencer Bridge Engineering was contracted to design, manufacture, test, and commission a semi-permanent access system that allows engineers to reach all stay cable elements.
The adjustable cradle system can operate across varying cable lengths and angles, maintaining level positioning during inspections. The project required dual compliance with European and Canadian standards and included the creation of a new winching and control system.
This milestone marks the final stage before on-site installation, ensuring long-term maintenance capability for the new bridge infrastructure.
