Question:
Why
are some bridges at the Village covered?
Answer:
One thing's for sure -- covered bridges were not built that way to
keep the snow and rain off travelers. And not all New England bridges were
covered. At the Village there are a couple of small bridges in the Mill
Neighborhood that aren't. The builders of covered bridges wanted to outsmart
Mother Nature and make their structures last as long as possible by protecting
them from New England weather. The covered bridge's roof and sides were easy
to replace. They kept wind, rain, snow, and sleet from the heavy beams and
timbers that supported the bridge load.
Ironically, it was
necessary to shovel snow onto covered bridges in the winter to let
sleighs and other horse-drawn vehicles pass over them. Only a few covered
bridges remain--as they deteriorated, they were replaced by concrete and
steel bridges, which don't need wooden covers to protect them.
