Ditch Bridges are made from aircraft grade aluminum, the Ditch Bridge is pre-engineered to handle large utility line trucks, cranes, drill rigs, etc. Available from 6' to 36', with a base rating for 65,000 lbs. trucks, and can be designed to meet whatever weight vehicle specifications you have. Because they are pre-engineered, the build time is reduced to a few weeks instead of months. This is the safe way to cross ditches and creeks using the equipment you plan to take to the field without having to bring specialized lifting equipment.
