"Bridge Plus Alpha" is a road widening method using steel substructures. The lightweight substructure units offer excellent workability, and the factory-manufactured units enable a reduction in construction and regulation periods. It has been widely adopted in many bridges across the country, including the Enoshima Ohashi Bridge. Even bridges that had given up on widening due to increased dead load with conventional concrete substructures can expand their possibilities with "Bridge Plus Alpha." Additionally, it can accommodate various functional additions such as drainage pits and lighting fixtures. Please feel free to contact us. We will prepare and submit an estimate of reference cross-sections, dead loads, material costs, and installation costs according to your requests. ● NETIS Registration Number: KT-230106-A
