There's no way to plan for Carmageddon, the three-day shut down of one of the most vital stretches of freeway in Los Angeles, without having to field some unusual requests or address oddball contingencies.
Take the Facebook group that has proposed holding a block party on a Santa Monica Boulevard ramp to the 405, complete with beer and guitars.
There's also the enterprising marketers who asked CalTrans for permission to spray paint a bridge abutment with graffiti reading "The Apes Will Rise" to promote the new "Planet of the Apes" movie.
A group of bicyclists sought permission to ride down the steep inclines of freeway in the Sepulveda Pass during the weekend closure. But those ideas ultimately were nixed because of safety concerns.
"In planning for this closure, we gathered the best emergency around," said Cmdr. Andy Smith. "We tried to think of everything but some of these requests are beyond even what we had anticipated."
