A long, slightly inclined limestone causeway connected the valley temple to the mortuary temple. The causeway was roofed, with narrow slits left in the ceiling slabs allowing light to enter illuminating its polychromatic bas-relief covered walls. These included scenes with seemingly apotropaic functions, such as a scene of the king represented as a sphinx crushing Egypt's enemies under his paw. Other scenes presented include offering bearers, animal slaughter, and the transport of the gilded pyramidion to the construction site. Only the base of the causeway, made of large limestone blocks, has been preserved.
