Isleton Bridge
Posted May 27, 2011, by Gloria Scott (Gloria [dot] Scott [at] dot [dot] ca [dot] gov)

Like the Paintersville Bridge, the Isleton Bridge was determined eligible for listing in the National Register of Historic Places as an excellent example of Strauss Heel Trunnion Bascule Bridge. Jenkins & Elton constructed the Isleton Bridge.
