You're right. After running the numbers it doesn't make any financial sense. At least they are spending our money on a hard asset used and built by working people, rather than wasting it on non-workers. This puts a serious $8.7 billion hole in the march to socialism.
Okay. 2000 working people at $150K per year for ten years is 3 Bil. Don't tell me the other 5.7 Bil is for materials! It's for non-workers.
(And I think it would be really tough to have 2000 people working at the same time on a tunnel.)
