SYRACUSE, N.Y. -- After Governor Andrew Cuomo and other local leaders demanded a second look at a tunnel to replace Interstate 81 in Syracuse, the results are in.

The tunnel option would take around a decade to build and cost billions of dollars. And while the Department of Transportation deemed it "technically feasible," others aren't on board with the idea.

This past January, a private study began taking a harder look at the feasibility of other options, like depressed highways and tunnels. That study was released Monday and revealed a depressed highway wouldn't be feasible. It concluded a tunnel option would be, but at a price tag of around $3 to 4.5 billion -- not to mention it would take nine years to build.

As for the alternative options: It would cost around $1.7 billion to rebuild the existing viaduct and around $1.3 billion for the street-level community grid. Representatives say they aren’t ruling anything out yet, and DOT officials say they will take their time to find the most fitting solution.

Meantime Syracuse Mayor Stephanie Miner is urging them to reject the tunnel option and focus on connecting the street grid. There is no set time table for a final decision.
