An explanation for why power lines fell onto the 405 Freeway last Thursday could take weeks to determine, a spokesman for Southern California Edison said Wednesday.
"As you can imagine with something like this, this is a complex matter," Edison spokesman David Song said. "A lot of times, it takes weeks on these. This isn't a typical case."
The lines fell Thursday afternoon near the Magnolia Street exit in Fountain Valley, shutting down much of the freeway for about two hours. The incident also knocked out power for about 2,500 local customers until about 3:15 a.m. Friday.
Edison is working with Caltrans on the investigation. However, Caltrans spokeswoman Yvonne Washington said Wednesday that Edison hadn't shared any information about a potential cause, and that there's no timetable yet for concluding the investigation.
