Syracuse, N.Y. - The State DOT has released a study about the feasibility of a tunnel to replace I-81.
The study considered two depressed highway options and seven tunnel options. The consultant for the study, WSP, concluded that both options for depressed highways were unfeasible. While a tunnel option would be technically feasible, it would cost between $3 and 4.5 billion and could take a decade to build. There would also need to be several parcel acquisitions to conduct a tunnel project.
Officials with the DOT will review the findings before making their recommendation.
