Beginning of the upper part of the ramp connection Wanapitei to Coniston. In order to reach Coniston, the roadbed climbs up the side of the aisle for Markstay, on the intermediate floor.

None of the notched joists are more than four feet long and do not support any structure, only a short section of flooring.
