Bridge falls as cameras roll.
Earlier this week in Glenwood Springs, Colorado, a section of a 64-year old bridge being torn down to make way for a new structure unexpectedly collapsed, endangering the Union Pacific tracks which run beneath it.
Demolition crews had been working on the bridge since Monday, taking down the Grand Avenue bridge piece by piece.
Around 8 pm crews at the south end of the bridge were pulling a girder out of the bridge when it got hung up on an anchor on a middle pier, between Seventh Street and the edge of the Colorado River, said Police Chief Terry Wilson. The pier buckled and then collapsed. The video below shows the collapse as captured on a live stream set up by Colorado Mountain College, located nearby.
