When heavy rains washed out an aging culvert, cutting off a residential neighbourhood in Vernon, BC, the Ministry of Transportation and Infrastructure needed to find a solution quickly. An assortment of pre-engineered, in-stock Atlantic Arches in our nearby Armstrong yard made it possible for us to offer immediate delivery and on-site assistance.
Open-bottomed design prevents future flooding
The failed 2 m round culvert was replaced with our 3.658 m open-bottomed Arch, allowing for a much better hydraulic flow to help prevent future flooding. Atlantic Arch stocked sizes range from 1.2 m to 4.2 m spans. The structure was shipped in nested sections with 16 rings assembled on-site and placed on the cast-in-place footings in less than a day. The contractor supplied the cast-in-place headwall and wingwalls on the upstream end.
Corrosion/abrasion-resistant Dur•A•Span
Atlantic Arches are made from Dur•A•Span Structural Aluminum Plate, which the client had never used before. Once made aware that it was corrosion/abrasion-resistant and that it had been successfully used in over a thousand installations worldwide, they were convinced. In fact, they were so pleased that they decided to use it for another culvert project.
