As a train travels towards downtown Boston along the Boston Elevated Railway at Forest Hills, a portion of the new Monsignor William J. Casey Overpass (Morton St.) is being constructed above. A commuter train on the former Boston & Providence Railroad route can be seen between the columns at the lower left. Notice the Metropolitan Police traffic booth on the sidewalk to the right. The booth was used by police who directed traffic during the morning and evening rush hours. Courtesy of Anthony Sammarco.
