Cars need somewhere to park. Buses and trains don't. The cost of building a car-only crossing across a major body of water only tells part of the story. Old buildings must be torn down if cars are to park in large numbers in cities.

The Golden Gate and Bay Bridges induced tons of automobile commuting into San Francisco. If each had instead been built as transit-only crossings, there would be far fewer parking garages and lots in San Francisco.

Building a vehicular crossing between Long Island and Connecticut would free some capacity between Queen and The Bronx and thus make it easier for people to drive into Manhattan.

Where are those people going to park?
