I think a priority for the next decade should be to build a neutrally buoyant tunnel that people can ride through in pods. Toronto to Niagara Falls (32 miles),Boston to Cape Cod (45 miles) Detroit to Cleveland (80 miles), Miami to Freeport (100 miles) Miami to Nassau (175 miles).
The Toronto to Niagara Falls would be the shortest. If you could do the crossing at 100 mph then transfer to a bus for the last 11 miles to the falls you should be able to do the entire trip in less than an hour. It wouldn't be much faster than the 90 miles by road, but it would be a reasonable length to develop the construction techniques.
We need some experience at slow speeds so that we can be more confident about building a neutrally buoyant tunnel at supersonic speeds.
