and exit numbers The original toll for the Harbor Tunnel Thruway was $0.40 (equivalent to $ in ) for passenger vehicles and $0.85 (equivalent to $ in ) for trucks. By 1985, the toll had risen to $1.00 (equivalent to $ in ). Electronic toll collection began at the toll plaza in 1999 for M-TAG customers; the M-TAG system was absorbed by E-ZPass in 2001. The MDTA increased the toll for passenger vehicles to $2.00 (equivalent to $ in ) in 2003. In May 2011, the agency announced the toll for the Harbor Tunnel Thruway and the two other harbor crossings would increase to $3.00 (equivalent to $ in ) on October 1, 2011, and to $4.00 (equivalent to $ in ) on July 1, 2013. The Harbor Tunnel Thruway has had three different exit number systems throughout its existence. The first numbering scheme was in place by 1963. The northbound exits were numbered between 1 (Holabird Avenue) and 5 (US 40), while the southbound exits were numbered 1 (Hanover Street) to 7 (US 1). The second numbering scheme, which did not change the interchange numbers on the northern approach to the tunnel, was introduced in 1971. The exits on the western approach were renumbered 11 (Hanover Street) to 17 (US 1). Under both schemes, the Childs Street exit did not have a number and the Moravia Road interchange was numbered as exit 1 of the John F. Kennedy Memorial Highway. The third and present numbering scheme was enacted in 1991. Exit list Auxiliary routes I-895 has two unsigned auxiliary routes, I-895A and I-895B. Both highways are portions of the southern approach to the Baltimore Harbor Tunnel that connects with the mainline of the Harbor Tunnel Thruway in Brooklyn Park. Both spurs are maintained by MdTA. I-895A and the portion of I-895B north of I-895A are part of the main National Highway System. The segment of I-895B between MD 2 and I-895A is a National Highway System principal arterial. I-895A I-895A is the designation for the connector between the northern end of I-97 just north of I-695 (Baltimore Beltway) and I-895B within Glen Burnie. The highway was constructed in 1957 to connect the northern end of the Glen Burnie Bypass with the Harbor Tunnel Thruway. In conjunction with the reconstruction of I-97's interchange with I-695, in which the loop ramp from I-97 north to I-695 west was replaced with a
