I-81 is important to the efficient movement of people and goods in and around greater Syracuse and is crucial to the integrity of the national transportation network. The purpose of the I-81 Viaduct Project is to address the structural deficiencies and non-standard highway features in the I-81 corridor while creating an improved corridor through the City of Syracuse that meets transportation needs and provides the transportation infrastructure to support long-range planning efforts. After careful consideration of a range of alternatives, FHWA and NYSDOT have studied the No Build Alternative, the Viaduct Alternative, and the Community Grid Alternative in this document.
