Oldcastle Precast Three Sided Bridge is a very competitive alternative to other types of small bridges and cast-in-placeunderground structures. Three Sided Bridge decreases the construction cost because it can be installed, backfilled, and surfaced in a very short period of time and are perfect for use in remote areas where ready mix concrete may not be practical.
Oldcastle Three Sided Bridges can be installed with little impact on the existing waterway, thereby protecting marine and nearby wildlife. Precast bridges also reduce the possibility of environmental damage over streams. They have the distinct advantage over concrete or metal culverts because the natural streambed remains intact so not to inhibit fish migration. When streams or tunnels intersect roadways at skewed angles, we adjust the skew to meet the exact angle.
