200th Street Bridge
Posted June 19, 2012, by Don Morrison (bacchus [at] mchsi [dot] com)

A few pictures of this bridge over the Wapsi at 200th street.

The bridge is closed to traffic at this time.

It has a flat deck with wood rails for the east approach, which also is partially over the stream. The bearings for the truss are mounted on pilings. The bridge is at a bend in the river, so erosion at the east end on the outside of the bend may be the reason for the closing.

The Wapsipinicon is a small stream this far north, and this bridge crosses it, not a branch.

Both bridge plaques are missing.

This is a nice tranquil little area surrounding the bridge.
