The Liberty Bridge in 1939, eleven years after opening to traffic. In many ways it looks the same as today. Back then, many of the inclines were still in service, connecting commuters to Mount Washington. The days of the incline, however, were numbered. Only two of the old inclines have survived the passage of time, the Monongahela and the Duquesne.

The Liberty Bridge in the early 1960's. The Mount Washington scenery hasn't changed much compared with the pictures above, with the noticable exception of the inclines, which have mostly been removed.
