The John James Audubon Bridge in St. Francisville has been named the top construction project recently completed in the United States by a national construction industry magazine.

In its Feb. 11 issue, the Engineering News-Record picked winners in 19 categories in its “Best of the Best” story about construction projects completed in the United States between July 2011 and June 2012.

The John James Audubon Bridge, which crosses the Mississippi River between Pointe Coupee and West Feliciana parishes, won “Editor’s Choice” as the top overall project in addition to winning the transportation category.

Engineering News-Record complimented the contractor’s “cofferdam design for the bridge using a combination of precast concrete panels and sheet piles” because of “variable water levels during construction.

“Once assembled, hydraulic jacks were installed, and the cofferdam was incrementally lowered 47 feet into the river,” the magazine wrote. “The team had never before attempted the maneuver at such a large scale.”

The bridge, considered to be the longest cable-stayed span in North America at 3,186 feet, now connects U.S. 61 to La. 1 as well as New Roads and St. Francisville, the magazine said.

Audubon Bridge Constructors, a joint venture of Flatiron Constructors, Granite Construction and Parsons Transportation, served as general contractor and lead designer of the project.

Louisiana TIMED Managers served as program manager. Engineers were Parsons Corp., Buckland and Taylor, Evans-Graves Engineers, Burk-Kleinpeter and GO-TECH.
