Joseph J. O'Brien, the cashier in charge of toll collection at the Sumner Tunnel, examines the toll recorder on December 23, 1940. When a toll was handed over, the least being 15 cents for a pleasure car and the most a dollar for a truck 10 tons or over, with a variety of amounts in between, lights would flash on the indicator pictured here which would tell the driver the tollman has just recorded the amount paid on his electrically operated toll register. When the tunnel opened the toll was 25 cents for cars but was lowered to 15 cents when the Chelsea North Bridge was closed in January 1935..
