How will the new bridge look?
You can click here to view an artist’s conception of the new Twin Span Bridge. The new bridge will consist of two parallel structures, each 5.5 miles long. Both bridges will be sixty feet wide and accommodate three 12-foot travel lanes. There will be 12-foot shoulders on either side of the travel lanes. The new bridge will be 21 feet higher than the existing Twin Span Bridge, and approximately 30 feet above the water level. The bridge will feature an 80 foot high-rise section to provide vertical clearance for marine traffic on Lake Pontchartrain.
