Covered bridges were covered for a reason- they were made of untreated wood. The shed like cover kept rain and snow off the structural members, and made them last longer. When we began making bridges of steel, we no longer needed the covering.
World Guide to Covered Bridges was created in 1953.

Hooded Bridges or "Covered Bridges" were important when horse travel was common. Horses are very reluctant to cross an uncovered bridge. They often will refuse to cross such a bridge, fearing they will fall into the water below. Covered bridges give the horse the illusion that they are entering a barn, because they cannot see the water below, and they do not balk crossing such a bridge.
