Louisiana Gov. Kathleen Blanco has ordered everyone still in the city of New Orleans -- many of which have been huddled in the Superdome and other rescue centers -- to leave.
As many as 25,000 people were going to be bused from the Superdome to the Houston Astrodome in Texas.
At the same time, sections of Interstate 10, the only major freeway leading into New Orleans from the east, lay shattered, dozens of huge slabs of concrete floating in the floodwaters. I-10 is the only route for commercial trucking across southern Louisiana.
