Bridge Collapse Aftermath

Road Closed

National Transportation Safety Board investigators met Sunday with Jefferson County officials. They're trying to find out what caused a girder to fall from a highway overpass Saturday.

CDOT spokeswoman Stacy Stegman said the girder collapsed after braces holding it in place gave way.

Three people were killed when the 40 ton girder fell on their SUV at an I-70, C-470 interchange near Golden.

Colorado Rep. Bob Beauprez says investigators are looking into the possibility of criminal tampering, but Jefferson County Sheriffs believe no foul play was involved.

East and westbound lanes of I-70 were reopened Sunday.
