The historic Franklin Avenue Bridge in Minneapolis, Minnesota, was built in 1923 and rehabilitated in 1970. The 1,050-foot-long, five-span, penspandrel concrete deck arch structure has served as a vital link over the Mississippi River for nearly one hundred years, connecting Minneapolis and St. Paul neighborhoods. Degradation and changing usage led to the full replacement of the deck and spandrel cap beams during the summer of 2016. By coupling accelerated bridge construction (ABC) techniques with prefabricated bridge elements and systems (PBES), the replacement of the superstructure was completed during a 116-day closure.
