Under the Bay

A few have written to me asking about going underneath the bay and whether or not a tunnel can be constructed underneath the bay.

Tampa Bay is a bit of a misnomer. It's not a bay at all... it's an tidal estuary because it mixes the fresh water from 4 rivers with the salty water from the sea in an area that is actually deeper than the body of water into which it flows. It's similar in many ways to the Hudson River, with the exception that New York already has public transit... and some of the best in the world :-)

Tampa Bay is, at its deepest point, only 45 feet deep. A tunnel dug 80+ feet underground would have more than enough clearance to go under the bay without disturbing the estuary.
