Callahan Tunnel

The Callahan Tunnel, officially the Lieutenant William F. Callahan Jr. Tunnel is one of four tunnels, and one of three road tunnels, beneath Boston Harbor in Boston, Massachusetts. It carries motor vehicles from the North End to Logan International Airport and Route 1A in East Boston. Ordinarily, this tunnel is only used to carry traffic out of the city, and with the completion of the Big Dig it only collects traffic from I-93 southbound (right after traffic merges from Storrow Drive) and downtown Boston. As of 2016, a toll of $1.50 is charged for non-commercial two-axle vehicles with a Massachusetts E-ZPass, while non-Massachusetts E-ZPass holders are charged $1.75. Vehicles without EZ-Passes are charged $2.05 through MassDOT's Pay By Plate MA program. For residents of certain Boston zip codes, a discount is in effect using an E-ZPass transponder, costing $0.20.Repair work to this tunnel had resulted in a complete closure, which began at 11 pm on December 27, 2013 and ended on March 10, 2014, two days before the scheduled reopening. A second phase of work took place between March 13, 2014 to late August 2014, resulting in a closure 11 PM to 5 AM. From August to mid-November 2014, work was finished during off-peak hours.AlternativesTraffic flowing between Logan International Airport and directions south of the city on I-93 and west of the city on the Mass Pike normally uses the Ted Williams Tunnel rather than the Callahan and Sumner Tunnels. Logan traffic can also use East Boston surface roads to and from Chelsea, Revere and Winthrop .
