The main entrance to the E-Quad is at the intersection of Olden and William streets. If using Apple or Google Maps, entering "Princeton Engineering" is more effective than entering a street address.
From U.S. 1, take Washington Road toward Princeton. Cross the lake and turn right at the light on Prospect Ave. This is the 3rd light after Rt 1. The first street to the left is Olden Street.
From the center of Princeton, take Nassau Street (aka Route 27) east, past Washington Road. Olden Street is the 2nd street on the right, and first traffic light, after the intersection with Washington Road.
Parking and Public Transportation
You can also park on Olden Street or on Williams Street in metered parking spaces. Williams Street is just past the Engineering Quadrangle on the right if entering from Nassau Street. There is also parking available on Prospect Street, at the end of Olden Street.
