They wanted to demolish a bridge in Marble Falls, Texas, USA. The video shows the whole process of the demolition, including a rather impressive slow motion version of the series of explosions.
It happened at 8:07 am on the morning of March 17th, 2013. The old US 281 bridge in Marble Falls, Texas quite literally bit the dust, or should we say water?
The video above was shot with a Nikon D800 & 85mm prime, and is accompanied by "Super Slow Motion" footage which was provided by a Canon SX260 HS point and shoot camera.
Quite an impressive sight to watch, as 3,000 - 4,000 onlookers count down to the final explosion. Even more fascinating to watch the slow motion version as the bridge slowly collapses into the water to the cheers of the people.
The concussions were louder and more forceful than even the experienced Texas Department of Transportation (TxDOT) officials on hand anticipated. This caused a sustained cry of "wow" and "awesome" from the onlookers on the shoreline after the demolition.
Howard Lyons, area engineer for the Texas Department of Transportation said after the explosion, “I didn’t expect it to be that impactful [sic].”
“I had pretty much been a party pooper about it not being that big a deal. But I’m glad I was here for that.”
According to Executive Director Phil Wilson of TxDOT, the bridge explosion was a rare event.
"This is probably the fifth bridge ever blown up in the history of TxDOT,” Wilson said. “It's the largest truss bridge at 600 feet."
"This was easier to do in 30 seconds than [what] would have taken three months to do otherwise," Wilson said.
The demolition of the bridge is part of a $30 million project to remove the existing four-lane bridge, built in 1936 and to replace it with two side-by-side, two-lane bridges, each with ample shoulders and 6-foot-wide sidewalks.
The crew reportedly temporarily relocated two ducks that bridge crews said had been hanging around the construction site for some time, becoming the project mascots.
Apparently the explosion damaged a sewer line which is suspended from the new concrete highway bridge just a few feet downstream. This delayed the re-opening of traffic on that bridge until 9 am, but the sewer line was repaired by 1:30 pm according to spokeswoman Kelli Reyna from the TxDOT.
The concussion also damaged a Verizon phone line crossing the river at that bridge. Although cellular and land-line services were still spotty on Sunday after the series of explosions, the phone problems were resolved later that day.
