I-81 is the primary north-south in New York. It runs from Pennsylvania to Ontario in the 1000 Islands, paralleling US 11 (formerly NY 2 prior to the establishment of the US route system). It is a major trucking corridor and is the main route for trucks running between New York, Ontario, and Québec. I-81 was originally a proposed extension of the Thruway. The elevated section south of I-690 in Syracuse is due for reconstruction and may be converted to a boulevard (with the remainder of I-81 to the north and I-481 swapped) or a tunnel. The details of the viaduct and removal alternatives are detailed in the Final Environmental Impact Statement.
