These structures are inexpensive to build and are easily maintained. Opentop culvert made from treated 6x6 timbers Another version of an open-top culvert. This version accomplishes the same objective as the white oak pole version but is more expensive to build. Open-top culverts do require occasional maintenance to maintain their effectiveness. The double open-top culvert was used in place of a standard culvert pipe.
Water flows through the channels during periods of wet weather.
This prevents the road from eroding and contributing sediment to streams. The conveyor belt water bar is built by placing old conveyor belt between two treated 2X6's. The structure is buried with the top of the 2X6's level with the road surface. Six inches of the conveyor belt is left above the surface of the road to divert water and sediment off the road. These structures are easy and inexpensive to build and are very effective.
