232nd Street Bridge

KWH Constructors played a key role in the successful replacement of the 232nd Street Bridge over the Alouette River in Maple Ridge, B.C., delivering a modern, resilient structure designed to meet both environmental and hydraulic challenges.

The original timber bridge was replaced with a new single-span steel girder bridge supporting precast concrete deck panels. Spanning 35 meters with no in-water piers, the design significantly reduces impact on fish habitat while also improving flow capacity. The increased elevation of the structure helps mitigate the risk of debris accumulation and log jams during high water events—an essential upgrade for long-term durability and performance.

KWH executed the steel erection using a 270-ton hydraulic crane, working efficiently from a single side of the crossing. The 20-ton girders were carefully lifted and set in sequence, ensuring precise alignment across the full span. This one-sided erection approach minimized site disturbance and streamlined operations in a constrained environment.

Following girder installation, KWH completed the placement of all precast deck panels, maintaining tight tolerances to ensure a clean fit-up and consistent riding surface. The combination of efficient erection methods and attention to detail resulted in a high-quality bridge structure delivered safely and effectively.
