A state study has found that a tunnel replacement of the Interstate 81 viaduct in Syracuse is feasible.
The study examined multiple options for a high-speed tunnel through Syracuse, combined with new city streets above ground to serve local traffic. The Save 81 coalition has been a major proponent of a hybrid tunnel option that incorporates both elements, particularly as state leaders seek regional consensus on the best path forward for the Interstate 81 project.
A tunnel would satisfy the need to maintain a high-speed route through Syracuse. Such a route allows travelers to efficiently reach destinations to the north and south of the downtown area. At the same time, new city streets would appease those who have sought a “community grid” option to replace Interstate 81.
An independent analysis of state data has shown that a community grid alone, without maintaining a high-speed option, would be detrimental to Syracuse and Central New York.
