A surface grade crossing structure comprising a series of flat rubber pads, each pad having a notch in the bottom to allow for easy installation. Adjacent pads are joined to each other by a key and keyway. Clips are placed in the keyway and secured in the railroad tie. The lower surface of the outer edges of each pad has a series of anchor reliefs which accommodate rail anchors at the base of the rail. The pads may be trapezoidal to accommodate both tangent and curved tracks.
