Map with all coordinates: The Callahan Tunnel (English Callahan Tunnel , officially Lieutenant William F. Callahan Tunnel ) is one of three road tunnels under the Boston Harbor in Boston in the state of Massachusetts of the United States through lead. The tunnel runs from Boston's North End to Logan International Airport and continues on Massachusetts Route 1A in East Boston .
The tunnel is usually only used in the north-easterly direction of travel and at the end of Big Dig only takes traffic from the I-93 in the south direction after the confluence of Storrow Drive . The tunnel was toll-free until 2016 . As of 2016, non-commercial two-axle vehicles are charged a fee of $ 1.50 with a Massachusetts E-ZPass, while users without a Massachusetts E-ZPass are charged $ 1.75. Vehicles without EZ Passes will be billed at $ 2.05 via MassDOT's Pay By Plate MA program. A $ 0.20 discount is available for residents of certain Boston zip code areas using the E-ZPass transponder. Traffic directed to the south usually flows through the toll road Sumner Tunnel, which runs parallel to the northwest .
Alternative routes
Long-distance traffic from the airport traveling south typically uses the newer Ted Williams Tunnel , which connects to the Massachusetts Turnpike and I-93 .
history
The tunnel was opened in 1961 and is named after the son of William F. Callahan , who was chairman of the former Massachusetts Turnpike Authority , who died in Italy just before the end of World War II .
Originally, a system of control signals was used in the Callahan Tunnel as well as in the Sumner Tunnel in order to be able to reverse one of the two lanes in the other direction in case the other tunnel had to be closed due to construction work or emergencies. With the construction of the Ted Williams Tunnel as part of the Big Dig , these measures became obsolete, but remained installed in the tunnels just in case.
