Drainage chutes, also referred to as over-side drains or curb slots, are commonly used at the ends of bridges to either prevent flow from running onto a bridge deck, or to prevent flow from running off a bridge deck onto the pavement. There may be other locations where a drainage chute or curb cut may be useful in removing flow from the pavement where no storm drainage system is present and where suitable outfall is present behind the curb and gutter section. In most cases, an opening in the curb connects to a scour-resistant channel or chute which prevents erosion of the embankment or slope. In some instances, the channel or chute may be replaced with a pipe placed in the roadway embankment as illustrated in Figure 10-8. This treatment facilitates mowing and other maintenance but also introduces its own maintenance needs to keep it from clogging.
