A slipform sled for paving street curbs and gutters has a hopper and a curb and gutter mold. A pivoting mold assembly having a standard curb elevation mold and a driveway curb elevation mold is mounted on the slipform sled. The pivoting mold assembly pivots on a shaft oriented parallel to the direction of motion of the slipform sled. Paving material is flowed into the hopper and is extruded through the standard curb mold or the driveway curb mold while the sled is moving providing a smooth uniform finish. Only the relatively small transition section between the standard curb and driveway curb needs hand finishing. The elevation of a vibrator in the hopper is changed to correspond to the elevation of the curb extruded.
