The primary study area for The I-81 Challenge is focused on I-81 from I-481 on the south to I-481 on the north along with the segment of I-690 from the West Street Interchange to the Teall Avenue Interchange. The overall study area for purposes of public participation and traffic modeling expands to cover the Syracuse Metropolitan Transportation Council (SMTC) Metropolitan Planning Area (MPA), which includes all of Onondaga County and small portions of Madison and Oswego Counties.  Within these two study areas different study limits were selected for the analysis of capacity and safety data and general social, economic and environmental features.
