Built in 1860, the Oregon Creek bridge is located near Highway 49 near North San Juan, California, being the oldest covered bridge in the state.  It has a total length of 101.1 feet w/ plenty of leftover graffiti.  The bridge was washed out in an 1883 flood & has been put back in placed, but in reverse from how it was originally built.  Today the structure has been deemed unsafe for vehicular traffic & sheet metal has been placed as a roofing protector.
