Building a bridge designed to submerge beneath the water at a site that floods regularly can be the most cost-effective solution.
Our low level concrete submersible bridges are built to handle a full highway load (HN HO-72) and withstand being over-topped several times a year. They are designed to maintain both water flow and fish passage and are considered a relatively low flood hazard risk. Installation of these slim profile bridges is straight-forward, and their low level can often avoid the need to obtain building consent.
Provide excellent strength to support heavy loads, such as vehicles and fully laden logging trucks.
Can be created and installed in waterway crossings with different widths and alignments. Beams can span up to 12m in length.
Designed to withstand temporary submersion during floods. Feature reinforced components to endure water pressure and debris.
Water flows over them during floods, reducing upstream buildup and supporting natural floodplain dynamics.
Modular precast concrete beams are made off-site. Quicker on-site installation reduced costs.
Low maintenance and durable concrete slab that resists water damage and erosion. Fewer repairs are needed compared to complex structures.

The Bridge It NZ team recently showcased their strong problem-solving skills and collaborative approach with two new low-level submersible bridge builds for Aratu Forests Limited, at their Kopua Forest in Maraetaha, Gisborne.
