Glulam arches and restorations, engineered for the Maritimes
In Canada’s highest-corrosion climate, WRD designs timber crossings and repairs that outlast steel, award-winning bridges built to a 75- and 100-year life.
The Canada Problem
Steel and concrete corrode fast here. Timber doesn't.
Steel and concrete bridges corrode fast in the Maritimes; timber, detailed and reinforced properly, doesn’t. WRD designs durable glulam crossings and in-situ restorations tuned to that environment, light enough to reuse existing piles and abutments, strong enough to widen a two-lane steel bridge into a three-lane timber one. The result is lower cost, less downtime, and a structure engineered to last generations.

Design methods, in brief
WRD designs restorations with high-strength-fiber systems that bond into a true composite steel can’t match, often doubling in-situ capacity; on new builds, engineered glulam arches deliver long clear spans at a light dead load. See our full design methods →
