Why were they covered? You can't take shelter in them. It's a bridge!

To protect the main timber trusses from the detrimental affects of rain/snow. The intermitant wetting and drying provided an ideal atmosphere for accelerated timber deterioration- rot. Large timber truss bridges were initially built in the United States without covers. It was not uncommon for such a bridge to fail within 10 to 15 years. There are original covered bridges still standing that have been in place since the 1820's.

it's covered so when rain or really stormy weather hit it would make the driver be able to see the road better...that way there are not many accidents on the bridge where it is harder to get help to them...

For horses. They would 'park' the wagons and buggys in them to rest the horses for a while when it was raining or snowing.
