A billion a mile? Wow, if that's accurate.

Edit: That number cannot be correct, FWIW.

Some quick research shows typical costs from ~$25M to ~$45M per mile.

Take the high number of $45M x 250 miles = $11.25B.

I'd gamble that the big casino owners could get it financed and probably make a pretty good case for the economics.
