As I mentioned in previous updates (most recently in Update #7), the bus box hole will eventually be about twice as deep as it is now. To accomplish it, bulldozers will push dirt into a hopper and conveyors will transport it to the surface where it will be stockpiled for later use as backfill.

One of the first steps in that process happened this afternoon with the placement of part of the conveyor system into the bottom of the hole. The photo below shows three conveyor parts in the hole and two more awaiting the crane.
