POOR BEARING CAPACITY OF SOILS DICTATES LIGHTWEIGHT BRIDGE

The Hale Boggs Bridge, located 12 miles upstream of New Orleans, Louisiana, is the longest of its type in this country, with a central span of 1,222 feet. Its design also provided an answer to the problem of erecting a relatively long-span structure in an area that has soils with limited capacity to support heavy loads. It is an orthotropic steel bridge deck supported by a system of diagonal cable stays, with a riding surface of 2-inch thick epoxy asphalt. Thin-walled towers of cellular construction anchor the cable stays. Smooth outside surfaces, devoid of stiffeners, and the use of weathering steel promote easy maintenance and inspection. This article discusses design of the bridge, its fabrication and erection.
