Culverts can be a very effective way to get water from one drainage ditch to the other side of the road when needed. Corrugated metal or plastic pipe, wooden open box top culverts or other suitable materials may be used. Culverts can be used in any size operation where cross drainage of water is needed.
Unlike rolling dips and broad-based dips, culverts can be used to safely transmit water from seeps, springs, and intermittent and perennial streams under haul roads and skid trails. They usually last a fairly long time if they are properly maintained and inspected for obstructions.
Although culverts are very good for most operations, they do have some disadvantages. Culverts can be expensive and labor intensive to install. They are also better suited for use on permanent rather than temporary roads.
