Movable Bridges - Knights Landing Bridge (2)

A view from the deck of the Knights Landing Bridge. In this view, we can see the top chord of the bascule span going through a slotted hole in the approach slab.  The trunnion must be a little bit in front of the approach slab, the counterweight sits below the slab, and it descends into the bin-like abutment when the operator raises the bridge.

This area has changed a lot over the years. When Dr. Knight first came here, this was a meeting place of Native Americans living along the Sacramento River and Cache Creek. A town and ferry were built to handle all the traffic moving along the river, but now its like a ghost town.
