Nine people lost their lives in the darkness and confusion, going off the highway into the creek's deep canyon, some despite being warned by one driver who had seen the first two cars go in ahead of him. as cars approaching the washout in the rain and dark did not know the bridge was out. The incident led to the highway's sobriquet, conferred by the

A coroner's jury recommended a series of measures to deal with highway safety, including warning lights at bridges where washouts may occur (this was never acted on), and 11 bridges along the route were replaced with structures with no support spans that might wash out in further debris torrents.

The location today was extensively rebuilt since the disaster, with the creek now bridged by freeway and a concrete structure, as with other hazards along the highway over the years since.

Three concrete "debris torrent basins" were constructed on the upper reaches of
Charles, Harvey and Magnesia Creeks to avert similar disasters emerging from those basins.
