Historic Bridges in the State of MaineIn 1959 the 99th Maine legislature
took a major step by enacting a law to preserve Maine's wooden
covered bridges. The new law provided that state money could
be used to save and renovate covered bridges. As a result, in
1961 the Department of Transportation undertook major renovations
to the 10 remaining covered Once
there were a hundred and twenty covered bridges in the state
of Maine, but fire, flood, ice, progress and the Great Freshet
of 1896 have removed all but eight original bridges. Two (2)
other covered bridges, recently lost to fire and flood, have
been reconstructed and are considered to have historical importance.
On March 26, 1983 the Morse Bridge in Bangor was destroyed
by fire; there are no plans to rebuild it. The remaining covered
bridges are scattered through out the state. The bridges were covered for one reason - to keep the rain and snow from the massive working timbers. The alternate wetting and drying out of uncovered wooden structures would have resulted in rot and failure decades sooner. Many people think of covered bridges as quaint relics of the past. Others become expert in describing the manner in which they were built. But, in either case, they represent the inventiveness and know-how of our forefathers, and it seems fitting that they should be saluted for their engineering as well as their charm. The ingenious way the old bridges were fitted together becomes apparent as soon as you pass through one of their portals. There, under the protecting roof, on either side, are the posts and crisscrossed braces extending from top to bottom "chord" (the chords are the heavy beams parallel to the line of the roadway). The planks of the floor are supported by the bottom chord in the typical covered bridge, which makes it a "through truss" structure.
