Alabama

[edit]

Mobile

  • Highways/Roads
    • Cochrane Bridge over Mobile Bay was hit by a flotel (floating habitat used by oil platform crews) that broke loose of its moorings. As of 31 August, it was determined that the damage was not critical, but only one lane (out of two) in each direction was opened. This is important due to the fact that the bridge is the I-10 Hazardous Materials route due to the underwater tunnels that cross under the Mobile River.
    • The causeway crossing the Mobile Delta (US Highway 90/98) was closed before the storm and was completely submerged during the hurricane. Parts of the causeway have been reopened while damage is being evaluated for the rest.

      • CNN video indicates that many segments of the Twin Span were either in the water or displaced 10-30 feet perpendicular to the road.
  • Levees
    • 17th St. Canal levee breached at Bellaire Drive and Spencer Ave
      • Mayor Ray Nagin announced around 6 pm on August 30 that the attempt to plug a breach in the 17th Street canal at the Hammond Highway bridge has failed and the rising water is about to overwhelm the pumps on that canal.
      • Efforts continued to plug the 17th Street canal resumed on August 31, after the water level had equalized with the lake.
      • At the Louisiana Department of Transportation's September 5 mid-day briefing, the 17th St. Canal levee repair was reported as complete. CNN's live video coverage throughout the afternoon continued to show the repair being reinforced with additional 3000 lb sandbags deployed by Chinook and Black Hawk helicopters.

    • London Avenue Canal floodwall was breached at 6100 Pratt Drive
