I-10 Twin Span Bridge, Bascule bridge across Lake Pontchartrain in Louisiana, United States.
The I-10 Twin Span Bridge extends 5.5 miles across Lake Pontchartrain with two parallel structures carrying six lanes of traffic between New Orleans and Slidell.
The current bridge, completed in 2011, replaced the original 1965 structure that Hurricane Katrina severely damaged in 2005, necessitating an $803 million reconstruction project.
The bridge received its official name, Frank Davis Memorial Bridge, in 2014 to honor the WWL-TV personality who frequently fished in the surrounding waters.
The structure features varying clearance heights from 30 to 80 feet above water, with lifting sections that allow marine vessels to pass underneath.
Parts of the original 1965 bridge now serve as an underwater reef and public pier in Slidell, contributing to local marine life conservation.
