The old bridge is closed, but the new bridge that runs parallel to the old one is open, connecting the Keys to the mainland. There is a museum and tour on Pigeon Key, located in the middle of Seven Mile Bridge.
The purpose of this bridge is to connect several islands. It was only one road from the mainland to Key West. Now this bridge open for pedestrians and fishers.
The purpose was to unit all the little islands and keys for the people can to trip through of them. Sorry my English isn't good.
The old bridge was closed because it fell into disrepair
We were told that it is under construction. And it used to be a train track about 100 year old.
