This week’s Pic of the Week takes us back to 2011 and the state of Iowa. This time to Spencer, where one of two Pennsylvania through trusses still exist. The Dump Road Bridge (also known as Old Rusty) spans the Little Sioux River at 18th Avenue west of the city. Built by the Clinton Bridge and Iron Works Company in 1901, Old Rusty was brought here in 1915 after having served Main Street crossing the same river along with another through truss span for 14 years. That crossing was replaced with a multiple-span arch bridge which was replaced by the current structure in 2008. Old Rusty still serves traffic but as a light-weight three ton crossing. Fitting to its location as very few cars cross the bridge. However, due to its age, one has to start considering its prospects as a bike/pedestrian crossing in the long-run.
