About: The State of I-81
I-81 was built in Onondaga County in the 1950s and 1960s. This means that portions of I-81 are nearing the end of their lifespan. In particular, it is the deteriorating condition of the 1.4-mile elevated section of the interstate in the City of Syracuse (the viaduct) that is the primary motivation for studying the future of I-81 at this time.
The viaduct is safe. The NYSDOT, which owns the road, inspects and maintains the 124 bridge spans that make up the viaduct on a regular basis. However, the time and cost associated with maintaining them in safe condition is growing. As this portion of the highway nears the end of its useful life, it is critically important to find more long-term solutions for I-81.
