Confusion Hill Bridges
The Confusion Hill Bridges (aka. Confusion Hill Realignment, Confusion Hill Bypass or South Fork Eel River Bridges) are a pair of high bridges carrying two lanes of U.S. Route 101 over the South Fork Eel River in Mendocino County in the U.S. state of California. The bridges were constructed to reroute approximately 1.7 miles (2.7 km) of the highway away from a massive landslide area on the south bank of the river. The north bridge was finished in July 2009 and the south bridge completed in September 2009; the whole bypass was officially opened to traffic in October of that year.
