Here are some photos of outdoor bridges with covering. They are located in the United States and Canada so you will need a map to find them all.
The purpose of covering is to shield the trusses and deck from the outdoor elements and make it last longer.
Most of these are over 100 years old as many were built from 1825 – 1900.
