While being prepared for demolition, the Grand Avenue Bridge in Glenwood Springs, Colorado unexpectedly collapsed to the railroad tracks below. Thankfully, no injuries were reported, but the local police chief said that workers had to flee the scene once the bridge section started to fall.
Crews were working on pulling one of the girders when a pier buckled and collapsed, according to the Post Independent. Clean up began almost immediately after the collapse. The concrete bed supported by the beams had already been removed from the section previously.
The original bridge was completed in 1953 and its replacement is partially built already. The total cost for the new bridge will total around $126 million.
It’s generally a good practice to set up a restricted access zone when there is any possible chance of collapse during demolition or wall construction. The cause of the collapse has not been determined.

A construction crane that was working on a highway widening project in St. Martin Parish in Louisiana collapsed onto the adjacent roadway last week, injuring one driver.
Demolition by implosion videos are always fun to watch. Adding an element of water makes them even more dramatic, though it’s probably not great for the ecosystem. Late last week, a one mile long, 23 year-old bridge in China was imploded in front of a crowd of spectators and caught on camera.
Cranes are an extremely useful and important piece of equipment on the majority of construction sites. They can also be extremely dangerous if they are not understood or respected.
As the US is experiencing our own natural disaster, by way of Hurricane Florence, China is being hit badly by a Typhoon Mangkhut. According to Independent, the storm has caused a crane, which was being used on a 22-story housing development, to crumble. That collapse was caught on camera by neighbors.
There have been a few devastating structural collapses across America and the world this year. In March, an under construction pedestrian bridge collapsed in Florida, killing 6. In Colombia, ten workers were killed when a large section of a bridge being built collapsed. Both of those tragedies happened while the structures were still being built, but a recent collapse in Texas has a bit of a different story.
If you’re a general contractor in the Davie, Florida area, I have an idea why one of your deliveries might have been late last week.
On Monday morning, a 13 story building in Miami Beach that was being prepped for demolition suddenly collapsed, injuring one Project Manager that was struck by debris.
In January of 2018, ten construction workers were killed and another eight were injured when a bridge spanning the Chirajara canyon in Columbia partially collapsed. That collapse has since been blamed on a poor design, reports have stated. Last week, the remaining sections of the bridge were demolished in dramatic fashion.
