(You can also look at the University's directions for general visitors.)
Binghamton is located near the intersection of Interstate 81 and New York Highway 17 (the future Interstate 86). The University is most easily approached from Exit 70-S of Highway 17. See the area map.
After exiting Highway 17, take Route 201 South for about 2 miles, moving to the left lane as soon as you get on. Stay in the left lane to the end where you will be on the ramp to Route 434 East. Stay in the right lane on Route 434 and the first right turn available is the main entrance to the campus. You may obtain a campus map at the information booth just inside the campus.

If you visit the campus between 5 p.m. Friday and midnight Sunday, then you do not need a parking permit to park at most of the surface parking lots on campus (except reserved spaces, or paid parking spaces).
Anyone parking on campus starting at 12:01 a.m. Monday through 5 p.m. Friday must display a valid parking permit or be parked in a paid parking space (the Parking Garage, the Paid Visitor's Lot or Metered Parking.) We recommend that you use the Parking Garage or the Paid Visitor's Lot. There are some Metered parking spaces across the campus whose availability is unpredictable.
The department is located in Whitney Hall, which faces the C4 center, just inside the loop road. It is within walking distance from the visitor parking lot (about 8-9 minutes). See the Google Map below showing several walking routes.
