The Houston Chronicle goes a bit overboard with the title to "Lessons come at high cost: 107 lives". It's about the evac of Houston before Hurricane Rita:
...But there was no plan for contraflow lanes, the mayor said. So, the city asked Gov. Rick Perry's staff in the middle of the night to get contraflow lanes working, and the effort got under way immediately after that.
Texas Homeland Security Director Steve McCraw said the state immediately responded to White's 6 a.m. Thursday request to open all Interstate 45 lanes to outbound traffic, but he admitted the effort could have been executed more efficiently. Hours elapsed as 700 troopers were brought in to close entrance ramps on the southbound lanes and other measures were taken to alter traffic flow.
Traffic on I-45 North already was gridlocked when they opened all lanes to northbound traffic. Interstate 10 was completely opened for outbound traffic several hours later...
Some experts rightly question their stretching to make some cases due to the evacuation.
