ABSTRACT:
A movable curb structure provides for easy access to a manhole structure wherein a permanent curb structure is substantially in line with the manhole structure by stopping the permanent curb structure on opposite sides of the manhole structure, forming a concrete pad behind and partially around the sides of the manhole structure, and removably mounting a cover box to the concrete pad with a front vertical wall of the cover box substantially in line with a back side of the permanent curb structure, and removably mounting a movable curb section to the front vertical wall of the cover box substantially in line with the permanent curb structure. Where the height of the permanent curb structure is different from the height of the movable curb section, the permanent curb structure is stopped some distance from the ends of the movable curb section so that the permanent curb structure can be blended either up or down to the height of the movable curb section depending on the relative heights of the permanent curb structure and movable curb section by providing tapered curb sections at the ends of the permanent curb structure.
