Early Sunday morning, a gasoline tanker exploded on a busy highway bridge in San Francisco. The heat caused the bridge to collapse, blocking two major highways.

According to the San Francisco Chronicle's blog (sfgate.com/cgi-bin/blogs/nwzch ...)

"Reader John Baynham says 'I was having trouble figuring out exactly where the crash site was so I created a Google map outlining the collapsed sections.'"

His public Google Map can be found here: maps.google.com/maps/ms?ie=UTF ...

There's also amateur YouTube video showing the fire that caused the collapse:
