From the West

Oh-oh looks like more permanent barricades are in place now.

Bridge still seems in reasonably good condition after the 2013 flooding.

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.
