There is bipartisan legislation to increase funding for passenger ferry service. It sounds like a good bill and maybe with the reauthorization of the highway bill coming up, it will be included in that.
I was reading CT is studying a $50B bridge from Bridgeport to Long Island . Would additional ferry service (there is a car ferry from Bridgeport to Port Jefferson) from maybe New Rochelle to Port Washington and from Stamford to Huntington be feasible?
Even if a Bridgeport - Long Island bridge is feasible, it would probably be 30 years before it is completed. Several companies are manufactured electric ferries now and I am sure NYC would like to see fewer cars drive through the the Bronx and Queens to reach destinations on Long Island.
