• Abstract:
  A new I-10 Twin Span Bridge was built over Lake Pontchartrain between New Orleans and Slidell, Louisiana to replace the old bridge ; that was seriously damaged from the storm surge associated with Hurricane Katrina (Category 3) that hit the southern part of ; Louisiana in August 2005. It was designed with higher capability to withstand extreme events such as hurricane storm surges and ; ship impacts. The new bridge is around 5.4-miles long located 300 ft. to the east of the old bridge with an elevation of 30 ft., 21 ft. ; higher than the old bridge, and an 80-ft. high-rise section near the Slidell side to allow for marine traffi c, making it less susceptible to ; high storm surge. The bridge consists of two parallel structures with three 12-ft. travel lanes and two 12-ft. shoulders on each side (60 ; ft. wide), allowing for a 50 percent increase in the traffi c volume. Some piers of the new bridge are supported by precast pre-stressed ; concrete (PPC) batter pile group foundations.
