The original 1937 Duchesnay Creek bridge, on the north-east edge of Lake Nipissing, was the last surviving timber deck truss bridge on Ontario’s highway system. Drawing on the heritage significance of the original, the newly completed replacement crossing on the Nipissing First Nation-North Bay boundary is the first structural timber bridge to be built in Ontario since that time. DTAH provided bridge architecture services for the design of the crossing, including 3D modelling and renderings to visualize the proposed design.
The bridge design features 12 glue-laminated timber girders supported on reinforced concrete piers, with distinctive curved timber bracing connector components. Above deck the bridge features an adapted open metal railing to enhance drivers views to the setting, barrier termination components with linear timber accents, cast-in “Duchesnay Creek” identity signage and enhanced roadway lighting.
