Tobin Bridge, Cantilever road bridge in Boston, United States
The steel truss bridge extends more than two miles across the Mystic River, connecting Boston to Chelsea with three traffic lanes on each level.
The Massachusetts Department of Transportation opened this bridge on February 27, 1950, following two years of construction at a cost of 27 million dollars.
The bridge received its current name in 1967 to honor Maurice J Tobin, who served as Boston mayor and Massachusetts governor during the construction period.
Electronic tolling replaced traditional toll plazas in 2014, allowing drivers to pay automatically through transponders or license plate recognition systems.
The structure features a double-deck design with northbound traffic on the lower level and southbound vehicles on the upper deck, spanning 800 feet at its center.
