The Bridge of Dreams

What is a covered bridge? If you know anything about covered bridges you know the major reason they are covered is to protect the wood trusswork supports from the weather. That is, however picturesque the result the reason for the cover is basically functional. The pictured bridge was built as a railway bridge in the 1920's. Later the right of way was converted to a bike trail and a cover added to the steel girder bridge in 1998. The cover is actually functional - not to protect the trusswork (there is none) - but to protect the people from falling from this high 4-span structure.
