Clean up of I-5 bridge collapse nearly complete

MOUNT VERNON, WA -- Washington state's Department of Transportation is working around the clock to get the collapsed section of the I-5 bridge cleared out.

On Thursday, a  tractor-trailer semi hit the overhead girder of the I-5 bridge causing the northern portion of the bridge to collapse.  Three people and two vehicles crashed into the river below.  No one was seriously injured.

So far, officials said about 2/3 of the clean up is complete. The hard part, officials said, is trying to get the bridge deck off the bottom of the Skagit River. This might require actually breaking into pieces before bringing it up.

The National Transportation Safety Board is continuing their investigation. Pieces of new bridge are now on sight, but can't be installed while the investigation is ongoing.
