The Huey P. Long Bridge in New Orleans, Louisiana will be officially completed in June this year, according to the LADOTD. A recent article in the Times-Picayune on-line announced another ramp opening last weekend, bringing the $1.2 billion project one step closer to completion.  DBA was brought onto the project by the contractor team to consult on the design, load testing, and construction of the 9-foot diameter, 184-foot long base grouted drilled shafts.

Check out our previous DBA posts on the HPL.

This article from the Times-Picayune in 2009 gives a great graphical description of how the bridge was widened.

You can learn all about the history of the bridge and the project at the project page of the Louisiana TIMED Program.  The project page has a lot of good links, including photos from the project.

The Huey P. Long Bridge over the Mississippi River in New Orleans was recently designated a National Civil Engineering Landmark by the American Society of Civil Engineers. From NOLA.com (via ASCE SmartBrief):

Representatives with the Society of Civil Engineers, including national president Andrew Herrmann, along with state Transportation Secretary Sherri LeBas are expected to attend. They will place a plaque on the bridge, distinguishing it as one of 250 such historic landmarks around the world. The honor places the Depression-era built bridge in the company of the Eiffel Tower, the Panama Canal, the Hoover Dam and the U.S. Capitol.

The $1.2 Billion bridge improvement project is one of several being managed by the Louisiana TIMED Program:

The TIMED (Transportation Infrastructure Model for Economic Development) Program is the single largest transportation program in state history. The TIMED Program was created by Act 16 of the 1989 Louisiana Legislature and was voted for by the people. The $5 billion improvement program includes widening 536 miles of state highways to four lanes on 11 project corridors, widening and/or new construction on three major bridges and improvements to both the Port of New Orleans and Louis Armstrong International Airport. The Program is designed to enhance economic development in Louisiana through an investment in transportation projects.

DBA was involved in the test shaft and base grouting program for the drilled shafts supporting the new pier added to supplement the existing piers of the bridge.  Check out previous posts here.
