The Maurice J. Tobin Memorial Bridge (formerly and still sometimes referred to as the Mystic River Bridge or less often the Mystic/Tobin Bridge) is a cantilever truss bridge that spans more than two miles (3 km) from Boston to Chelsea over the Mystic River in Massachusetts. The bridge is the largest in New England. It is operated by the Massachusetts Department of Transportation and carries U.S. Route 1. It was built between 1948 and 1950 and opened to traffic on February 2, 1950, replacing the former Chelsea Street Bridge. The 36-foot (11 m) wide roadway has three lanes of traffic on each of the two levels with Northbound traffic on the lower level and Southbound traffic on the upper level.

Description
The bridge is a three-span cantilevered truss bridge at 1,525 ft (465 m) in total length. The center span is longest at 800 ft (244 m) and the maximum truss height is 115 ft (35 m). There are 36 approach spans to the North and 32 to the South. The roadway is seven lanes wide between the shortest (439 ft; 134 m) span and the center to accommodate the now-unused toll plaza. The Northbound toll plaza was closed in the 1980s; the Southbound toll plaza was closed on July 21, 2014.

History
The bridge was originally operated by the Massachusetts Port Authority, which, according to the original plan, was to remove the tolls once the $27 million in bonds used to finance the bridge's construction were retired in 1978. Instead, the tolls were increased to 25 cents to cover the closing of the Northbound toll plaza in the 1980s. Starting in the early 1990s the tolls increased sharply to help pay for the Big Dig. As of October 28, 2016, the toll is $1.55 for non-commercial cars traveling in either direction ($1.25 with an E-ZPass issued by any toll agency, and $0.15 for registered residents of Charlestown and Chelsea with an E-ZPass).
In 1967, the Mystic River Bridge was renamed in honor of Maurice J. Tobin, former Boston mayor and Massachusetts governor. During his term in office (1945-1947), Tobin created Massport and ordered the construction of the Mystic River Bridge. Tobin went on to serve as Secretary of Labor under President Harry Truman before he died in 1953.
In 1973, a gravel truck traveling over the lower deck crashed into a support, collapsing the upper deck onto the truck and killing the driver. Later that year, the bridge reopened after more than two months of repair.
On January 4, 1990, racial hoaxer and double murderer Charles Stuart committed suicide by leaping from the bridge.
Legislation was passed to transfer the bridge from Massport to the new Massachusetts Department of Transportation, effective January 1, 2010.
On the morning of July 21, 2014, the bridge's tollbooths were closed and eventually removed for an all-electronic and cashless tolling system, and from that point on all toll charges are paid for via either E-ZPass at the current rate, or "pay-by-mail" where an invoice will be sent to motorist's home via license plate number recognition at the former cash toll rate. This inaugurated a 2½ year process by MassDOT which converted all of the toll roads and bridges throughout the Commonwealth to automatic open road tolling.
Restorations
In September 2017, the Massachusetts Department of Transportation announced a three-year $41.6 million project to restore the bridge deck, steel repairs, and painting a portion of the bridge. The first phase of work will start in April 2018 and run through November of 2018 and will be conducted again during the months of April - November for the next two years, ending in 2020. The work will be done by J. F. White Contracting Co.
