Interstate 895 (
I-895) is an
Interstate Highway in the
U.S. state of
Maryland. Known as the
Harbor Tunnel Thruway, the highway runs between one junction with
I-95 in
Elkridge and another interchange with I-95 on the east side of
Baltimore. I-895 is a
toll road that crosses the
Patapsco River estuary via the
Baltimore Harbor Tunnel, connecting
U.S. Route 1 (US 1),
I-695, and the Baltimore–Washington Parkway in the southwestern suburbs of Baltimore with
US 40 on the east side of Baltimore. In conjunction with a pair of spurs,
unsigned I-895A and I-895B, I-895 provides access to the tunnel from
I-97 and
Maryland Route 2 (MD 2) in
Glen Burnie. The highway is designed for through traffic by having partial interchanges that require vehicles from almost all starting points to pass through the tunnel and the tunnel toll plaza, where a $4 toll is charged to passenger vehicles, before exiting the facility.
