Greencastle Avenue Bridge


Greencastle Road Bridge

The bridge is in a very eerie setting because the surrounding area was so stripped by the June 2008 flood.

According to an Press-Citizen article from December 1st, 1950, they intended to replace the bridge after the completion of the Coralville Dam due to an north approach being damaged on November 4th of the same year

Nothing ever seemed to come of it, fortunately.

People come through and say "Hey check out my bridge." so I do and this one is very sad. Maybe it should go somewhere else.
