ABSTRACT ONLY:
Hurricane Katrina knocked parts of the bridge carrying U.S. Route 90 over Biloxi Bay, in Mississippi right off their piers and into the rapidly moving water below. When the storm retreated, engineers were left to design and construct a replacement crossing that had to have one lane in each direction operational in just 18 months and three lanes in each direction operational in less than two years. The design/build project delivery method made it possible.
