Colorado Flood Shuts Highway With Damage ‘Unlike Anything’ Seen Before

Well, it’s lastly infrastructure week and never a second too quickly. On Sunday, Colorado’s essential east-west artery of I-70 shut down indefinitely “due to extreme damage from the latest round of flooding” to hit the state.

Heavy rains fell, unleashing a torrent of particles onto I-70 close to Glenwood Springs. It’s the newest in a summer season of infrastructure failures tied to excessive floods from Detroit to giant swaths of Europe. But this one comes with a diabolical twist: The heavy rains fell on a wildfire burn scar from final yr, displaying how local weather change impacts can compound and make a foul state of affairs worse.

The particles circulation is the worst but to strike the area. State roadway managers have been closing stretches of I-70 within the burn scar space all through the summer season every time flash flood warnings have been issued. (There’s one more one in place for Monday with heavy rains strafing the area.) More than 100 motorists were trapped on the interstate through the storms and particles flows, although fortunately all had been rescued with out incident. The injury wrought late final week dwarfed earlier cases of flooding on the roadway, main the Colorado Department of Transportation to close down the freeway to take a better look.

“This assessment was provided by senior operations supervisors and engineering staff who described damage to the viaduct structure unlike anything they had seen before,” mentioned on Facebook.

Images present concrete ripped from the roadway and guardrails whereas bushes and rocks clog the roadway. Aerial video captured by Fox 31, the native affiliate, additional reveals the injury with rocks and particles thickly piled up round relaxation storm indicators as crews clear a path. The interstate will stay closed till a minimum of this weekend, forcing these touring it to take a detour that may add hours to any journey by means of the realm and additional snarling provide chains. It all feels wearily acquainted. Heavy rains blitzed Detroit earlier this summer season, resulting in flash flooding that turned highways there into canals. Even extra widespread and damaging floods have ripped by means of areas as distant as China and giant parts of Europe in latest weeks as properly.

Climate change is growing the percentages of heavy downpours since a warmer environment can maintain extra water. That’s all properly and good… till mentioned water exits the environment in deluges that may cowl roadways in water or rubble (or each). Heavy downpours have elevated in every corner of the U.S., together with Colorado. But the state—and others throughout the West—are seeing these downpours fall on prime one other hallmark of local weather change.

The Grizzly Creek Fire was amongst quite a few blazes that lit up Colorado final yr, together with two of the state’s largest on information and one hearth that marched over the crest of the Rockies in October. (To be clear, that could be very dangerous and really not regular.) It matches with a pattern of more and more giant and harmful wildfires that may go away slopes denuded and destabilized. That, in flip, will increase the percentages of even average rains unleashing particles flows like those which have closed I-70.

American roads currently get a D grade from the American Society for Civil Engineers, with Colorado particularly solely faring barely higher with a C-. The bipartisan infrastructure proposal unveiled on Sunday evening would enable states to spend as much as 15% of funds from the Highway Trust Fund—at present funded to round $500 million yearly—on addressing flooding points, together with transferring roadways. The proposal additionally has a handful of different flood provisions as properly, together with defending infrastructure from coastal flooding as properly. But it’s the tip of the iceberg of what’s wanted. (Don’t even get me began on public transit.)
