Bridge Out

Tyco in your description you say "This bridge is on an abandoned track that used to serve a port that has been filled in with silt."

But it looks like an active line to me. Can you back up your claim that this line is abandoned?

The Master Plan for the area of Westport calls for it to be turned into a pier (page 47). in discussions with the developer (Patrick Turner) of the waterfront properties it will be turned into a walking bridge to complete a 5 mile loop around the Middle Branch. There are active tracks around this bridge but this is not an active line.

Follow the tracks to the left and you will see they end in a paking lot.

New news article on reusing this bridge for a 5 1/2 mile walking trail.
