The existing 90-year-old Johnson Street Bridge is located at the heart of Victoria, B.C. and is in the process of being replaced with a new bridge that will serve the community for the next 100 years. The new bridge is being built adjacent to the existing bridge, allowing the important transportation connection into Victoria's downtown to remain open during construction. The new bridge design includes a 25 meter long by 20 meter wide bascule pier box which will house the mechanical and electrical componentry for opening and closing the bridge span across the marine harbor.

The 1,100 ton bascule pier box is comprised of a steel and concrete caisson which needed to be lowered upon 16 large piers with tight precision.
