After completion of the post-Katrina assessment to the I-10 Twin Span Bridge and emergency repairs to reopen the bridges, Volkert was selected for the Construction Engineering and Inspection (CEI) of the new I-10 Twin Span Bridge over Lake Pontchartrain for the Louisiana Department of Transportation and Development (DOTD).
The new bridge, completely funded with federal dollars, was built 300 feet to the east of the current bridge. It was the largest public works project in the history of Louisiana. The bridge was designed for a hundred-year life and with reinforced concrete walls to increase storm surge resistance and minimize the effects of any barge collision. It is the first bridge in Louisiana to be built entirely with high-performance concrete. An average of nearly 55,000 vehicles per day traveled the 5.4 miles across Lake Pontchartrain on the twin spans prior to the storm. The new bridge allows for a fifty percent increase in volume.
Volkert was responsible for CEI of the entire structure including fabrication inspection. Volkert developed and maintained the website to keep the public informed of the progress of the project, traffic delays, and alternate routes. The new Twin Span bridge was opened for operations nearly a year ahead of schedule.
