The Baltimore Harbor Tunnel

The Baltimore Harbor Tunnel carries Interstate 895 underneath the Patapsco River, offering a key bypass route around downtown Baltimore. Opened in 1957, this four-lane toll facility provides a direct connection for regional highway traffic traveling through Maryland. Drivers pass through using cashless electronic tolling, making an E-ZPass transponder or Pay-By-Plate account essential for seamless travel.
