Isleton Bridge is a historic bascule bridge carrying California State Route 160 across the Sacramento River north of Isleton, California, built in 1923. There are two concrete tied arch spans, each 102 feet (31 m) long, to the east of the main bascule span, which is 226 feet (69 m) long, and four concrete girder spans.
