My tax dollars at work. Two million dollars to study an idiotic idea that makes no sense whatsoever on any level other than make-work for the unions. The point of this tunnel would be....what? For better traffic flow thru Syracuse? You can already go around it on I-481. I pass thru here quite often. The few extra minutes on 481 vs. 81 are insignificant and negligible, altho I cant speak for rush-hour traffic on either. And $4.5-billion & 10-years to complete really means $6-billion and 15 years. The I-81 / Route 17 interchange in Binghamton has been under construction over 6 years now without an end in sight. Thats a freekin nightmare on weekends when the snowflakes go back to school.
See #22 and #24 for my solution to the problem.
As for tunnels, think Big Dig or that Bertha tunneling machine mess in Seattle.
