Monolithic Bridges

Image: Each bridge section is independent and designed for full highway loads. Any number of sections can be used to create bridges for small to wide waterways. They can be like the old Roman viaducts.

Image: Each bridge section can be wide or narrow. They can actually move more water if they are spread apart as shown.

Image: Monolithic Bridges are a safe, long-term solution. Virtually indestructible, these concrete bridges won’t burn, or buckle, and the concrete will last longer than anything made of wood or steel.

Image: As an option sloped ends fit the contour of most rural roads. Maintenance is relatively simple by use of rip rap. Generally the tunnel can be cleaned out at low water by using a skid steer.

Image: Note how well the sloped end Monolithic Bridges fit into the topography of the roadway. The simplicity is a huge factor in the affordability and versatility of the Bridges. They are fast to install. They will take enormous abuse as well.

Image: This simple sketch shows one of an infinite number of profiles. The Monolithic Bridge can be of any length and a wide variety of heights and widths. The sloped ends can also be varied or left off.

Image: Compare the two 8.5 foot diameter metal culverts with a Monolithic Bridge section. The two will carry about the same amount of water. The bridge will last eons longer, carry more load, and allow more trash to pass. And the bridge with sloped ends is far easier to maintain and will generally be less costly.

Image: Figure A — Generally, Monolithic Bridges are constructed to meet the building code for highways and bridges as written by AASHTO (American Association of State Highway and Transportation Officials). The heaviest loading for a short-span bridge is designated as HS 20-44. The AASHTO code showing this loading is included.
