WINGPOINT CONCRETE CULVERT-TO-BRIDGE CONVERSION

PROJECT OVERVIEW

At Wingpoint, Rycroft Construction was engaged to replace a collapsing culvert with a permanent, reinforced concrete bridge structure. The project involved constructing a heavy-duty concrete slab directly over the existing culvert, ensuring continuous and safe access even once the culvert failed. The result is a low-maintenance, long-term solution designed to handle regular rural traffic and variable ground conditions.
