Aerial panorama near the New Orleans Superdome from a helicopter 1,000 ft. above Hwy. 90/S. Claiborne Ave. at Martin Luther King Jr. Blvd. This is almost a month after Hurricane Katrina and three days after Hurricane Rita, which accounts for the almost deserted streets and highways and the eerie ghost-town look. The Greater New Orleans Mississippi River Bridge is normally the fifth busiest toll bridge in the country.
