Curbed ramp
A ramp system includes a rail with an outer wall that defines an extent of the ramp in a width dimension. The rail includes an inner wall that is connected to the outer wall at a curb head. The inner wall extends away from the curb head at an angle relative to the outer wall. A side wall is oriented parallel to the outer wall. A lower end of the side wall is connected to a lower end of the outer wall by a bottom wall. A shelf is connected between an upper end of the side wall and a lower end of the inner wall. The shelf extension is connected between the lower end of the inner wall and the outer wall. A deck is secured to the shelf.
