Location Map

The John James Audubon Bridge or simply the Audubon Bridge is a cable- stayed bridge in the United States, located in the state of Louisiana.

Characteristics

The Audubon Bridge spans the Mississippi River at St. Francisville, about 35 kilometers northwest of the capital Baton Rouge. It is a cable- stayed bridge, currently the largest in the United States, with a total length of 3,927 meters and a main span of 482 meters. The bridge pylons are 152 meters high and the free passage under the bridge is 40 meters. The part on the east bank in particular has a large number of bridges. Over the bridge runs State Route 10 in Louisiana with 2×2 lanes. Despite its size, the bridge is only of regional importance. The bridge is toll-free.

History

Previously, there were no fixed connections between Baton Rouge and Natchez for about 150 miles of river, only ferry services, including the Mississippi River at St. Francisville. The bridge was constructed between 2006 and 2011 and opened to traffic on May 5, 2011. When opened, it was the largest cable-stayed bridge in the United States and the Western Hemisphere. Due to the size of the bridge, the road has 2×2 lanes, but the connecting road sections are single lane with oncoming traffic. The bridge is built over one of the narrower points of the Mississippi River, where the river is just under 600 meters wide in the summer. Construction of the bridge cost $409 million. The bridge is named after John James Audubon (1785 – 1851), a French-American ornithologist.

Traffic intensities

In 2011, the year of opening, 3,100 vehicles crossed the bridge every day. This low number is because there are no major towns nearby and State Route 10 has no major through importance.

When it opened, the bridge did not yet connect to other roads and was called a “bridge to nowhere”, although the bridge later managed to shake off that image, nowadays the bridge is used fairly intensively for an underlying connection. The bridge was originally a toll road, the toll was removed in 2001.

Traffic intensities

In 2012, 22,000 vehicles crossed the bridge daily, a relatively high number given that larger towns are fairly far from the bridge, and it is mainly local and regional traffic that crosses the Mississippi River here. In 2000, when tolls were still levied, 13,000 vehicles used the bridge every day.
