Photograph album documenting the construction of the Bacon Island South, Pratt through-truss, swing bridge in San Joaquin, California, ca 1905
A bridge construction album made-up and photographed by someone with access to the construction site. The Bacon Island South Bridge is a pin-connected swing bridge with a 326 foot span and an unusual truss configuration to support the extension out from the pivot. The album shows all the details of construction, the pivot mount and its movement, movement of truss sections into position at the site, erection, barges and steamboats on the river, truss details etc.
