Planning an eruv route is a challenging and exacting task, which requires weighing multiple Halakhic, pragmatic and other issues. With this in mind, the present route has been selected primarily to enclose the entire Cornell campus, dormitories, Collegetown, and major Ithaca synagogues.
Below is a map of the eruv route. One should assume that all streets marked as boundaries are not included as part of the eruv. If you need further clarification, please contact Rabbi Ami Silver.
