ENR’s Best of the Best 2012–Audubon Bridge

ENR Logo

 

The John James Audubon Bridge was recently selected as the Editor’s Choice/Transportation for ENR’s Best of the Best Projects for 2012.  The annual competition culminated in honoring ENR’s selection of the most outstanding construction projects in the U.s. And Puerto Rico complete between July 2011 and June 2012.

Nearly 1,000 project teams submitted their best work to ENR’s regional "Best Projects" competitions. For each of the nine regions, our editors assembled an independent panel of industry judges to home in on the winners in 19 categories. The winners of the regional contests moved on to the national competition. A different set of industry judges examined the projects to distinguish the "Best of the Best" in teamwork, success in overcoming challenges, innovation and quality. This year, a new award honors the safest project, judged by industry safety experts in both the regional and national competitions. Also, ENR’s editorial staff chose one special project as the "Editors’ Choice" to represent the pinnacle of design and construction excellence.

The Audubon Bridge won the Editor’s Choice – the editorial staff’s selection of the “pinnacle of design and construction excellence”.  Congratulations to everyone at Audubon Bridge Constructors (Flatiron, Granite and Parsons), Louisiana DOTD, and all who worked on the project!

Regular readers of our blog will be very familiar with the JJA as we often called it.   You can catch all of the geotechnical and foundation highlights on our project page, or check out previous posts.

The John James Audubon Bridge between New Roads and St. Francisville, Louisiana was officially completed February 27, 2012.  The bridge was opened to traffic in May of last year, but was declared officially completed last month.  This bridge has a special spot in the heart of DBA as it was one of the early large bridges we worked on as a company.  Steve and Dan poured their energy and expertise into the project starting in spring of 2006, all the way to completion of the last foundations in 2010.  Steve spent a good part of his life on site during foundation construction.  I spent a fair amount of time there myself helping Steve cover things now and then, including observing the soil borings for the main tower piers during the design. 

The JJA (as we like to call it) was the subject of one of my early posts when we started this blog in early 2006.  You can scroll through the many posts made during our work on the project here, starting with the soil boring program.

From the press release posted on the TIMED Audubon Bridge site:

Construction on the John James Audubon Bridge has officially come to a close. The new Mississippi River crossing is the longest cable-stayed bridge in the Western Hemisphere, with a 1,583’ main span. Located in south-central Louisiana, the Audubon Bridge connects West Feliciana Parish with Pointe Coupee Parish and is the only bridge between Baton Rouge and Natchez, Mississippi. Construction on the $409 million project began in 2006 and continued when the bridge was opened in May 2011 due to high water levels closing the St. Francisville Ferry sooner than expected.

"Although the Audubon Bridge has been open to traffic for nine months, it’s with a great sense of accomplishment that we are announcing the end of construction on this beautiful structure," said Department of Transportation and Development Secretary Sherri H. LeBas, P.E. "The completion of this bridge opens economic development in south-central Louisiana and will be a source of regional, statewide, and national pride."

Dan ran across this blog entry from Angelle Bergeron, a freelance writer in New Orleans writing as the New Orleans correspondent for Engineering News-Record.  Check it out.

Personally, I look forward to making a trip through the area and getting to cross this beautiful structure.  Hats off to Audubon Bridge Constructors, a joint venture of Flatiron Construction, Granite Construction and Parsons Transportation Group, for a job well done!
