There are several visitor parking options on campus. On Saturdays, metered street parking is usually available. Moreover, hourly pay-by-plate parking is available to any guest, student, or employee of the University. Payment is required all hours, all days, except for official university holidays. Self-service pay stations do not provide change. The Fifth Avenue Parking Lot is the closest lot to the Oregon Number Theory Days meeting; see the campus parking map for locations and rates. Here are frequently asked questions about pay-by-plate.
