New Jersey Transit bus routes 161, 163 and 164 provide service to and from the Port Authority Bus Terminal in Midtown Manhattan; the 76 line serves Newark; and local service is offered on the 709 and 780 routes.
In addition, NJ Transit provides rail service via the Pascack Valley Line's Williams Avenue station, which is located on the boundary of Hasbrouck Heights and Teterboro. Although the rail line's tracks lie entirely within the municipal boundaries of Hasbrouck Heights - and in fact form the borough's eastern boundary with Teterboro - NJ Transit considers the station to be in Teterboro because its parking lot and ingress/egress roads are accessed from that town.
Route 17 and U.S. Route 46 both pass through Hasbrouck Heights.
Portions of Teterboro Airport are located in Hasbrouck Heights.
