Our 3-sided bridges are suitable for a variety of applications including marine construction, wildlife crossings, riding trails, golf courses, and more. When streams or tunnels intersect roadways at skewed angles, our bridges can be installed to adjust to the skew to meet the exact angle. Optional configurations can include our precast wing walls.
