A dramatic mix of giant road crevices and an underground landslide on U.S. Highway 231 near Huntsville, Alabama, in the early morning hours of February 13, closed about 1,000 feet of the main four-lane highway.
Alabama Gov. Kay Ivey temporarily declared a state of emergency to restart the paintings and create detours, mask the pain, and expand a sustainable plan to fix the route.
Since then, the Alabama Department of Transportation has overseen efforts to rebuild the road along one of the Brindlee Mountains, a chain of hills in the domain with elevations up to 1,300 feet high. The destroyed component of the highway is located seven miles south of Huntsville, near Laceys Spring in Morgan County. No one was injured by the slide.
After reading the cause of the accident, engineers discovered that the slide was approximately 50 feet below the roads north and south. It was discovered that the cracks and fault imaginable of the road were the result of heavy rains that hit northern Alabama during the winter and fell further during cleanup operations.
As a component of emergency procedures, ALDOT awarded the contract for the first phase of U.S. Project 231. A Reed Contracting Inc., a heavy-duty company with experience in Huntsville. The manufacturer jumped straight into the fray through the damaged road from the site the day after the state closed the road. Since then, Reed has been working seven days a week, weather permitting, to dig and transport debris.
The estimate of the paintings is that the reconstruction will cost about $18 million and can take up to a year, according to ALDOT. The state earned $5 million in emergency investment from the Federal Highway Administration in mid-March to begin construction. ALDOT expects more federal aid by the end of the year.
The schedule, of course, is daunting for motorists and truckers who have U.S. 231 to get to Huntsville from the south. The largely rural highway is also an important link for alabama-traveling drivers from Tennessee to southern points, adding the cities of Dothan to Panama City, Florida.
To help alleviate traffic problems, 4 diversion routes through ALDOT have been established for passengers and advertising travelers in the direction of the broken area.
ALDOT from the outset that an undeniable road reconstruction would not work, as it may mean that the United States 231 would remain vulnerable unless the slippage was somehow mitigated. Digging at the intensity of sliding, filling and road reconstruction would provide no guarantee against long-term landslides.
Money and time are other points that oppose a road restructuring. Even moving the road to a new logo location would be unattainable, expensive and would take years. Changing the road route would involve time-consuming studies, road rights acquisition, and environmental approvals, all before design and structure can begin.
Instead, ALDOT’s plan focuses directly on the affected 1000 feet of road and will permanently technify the sliding zone to convert the US 231 to motorists. The shipping company also believes that the solution can be implemented in a relatively short period of time, given the magnitude of the problem.
Engineers and geotechnical experts said the most productive course of action was to build two 1,000-foot-long bridges that are enlarged along the sliding zone on existing road layouts. According to ALDOT, bridge structures in drilled wells will protect them from long-term slips.
Offers for the bridge paintings will open in early May, said Curtis Vincent, ALDOT engineer from the North Region. Once this is done, the state will notice continuing with the winning bidders approximately a week later.
“We anticipate that the entrepreneur or marketers will mobilize immediately,” Vincent added. “A delay of 12 months is an estimate of paintings. We expect that with the incentives attached, the structure time will be between six and nine months.”
Each of the two new U.S. 231 bridges will measure 44 feet wide from one gutter to the other (two 12-foot rails with 10-foot maples). They will have 8 pillars (two donkeys and six elbows), anchored through two wells, for a total allocation of 32 wells. The teams will install wells 7.5 to 8 feet in diameter and dig about 15 feet into the healthy rock under the slide.
“I think this component of the task is unique, as we upgrade 1000 feet of pavement in the appearance of a mountain with two bridges, which will be embedded in forged limestone to prevent any long-term movement due to surface sliding. Diapers, Vincent explained.
The $18 million allocation is an estimate of paints because the final design of the bridge is still being completed, he said, adding that ALDOT had to pre-order and pay $2.4 million for the beams and platforms to move the fountain and structure forward quickly.
Meanwhile, Reed Contracting has lately been striving to move tons of rock, dirt and asphalt from the affected area. More than two months after the slide, more than 100,000 cubic feet. Yds. were removed from the site, despite Mother Nature’s delaying tactics. This number is approximately one part of the number of curtains that will be removed from the site.
“We continue to see heavy rains in northern Alabama, but Reed continued to paint well and made wonderful progress, with approximately 50,000 cubic yards of curtains dug in the first 3 weeks alone,” Vincent reported. “Rainy weather was the most shocking level of the level from which we received data on the slide, as wet and muddy situations slowed the drilling because of protection issues and made it difficult to access certain spaces of the site for the platforms.
To date, Reed Contracting has brought six excavators, 20 trucks sold, five giant rock conveyors and other appliances and machinery to perform the task.
ALDOT Northern Region Public Affairs Officer Seth Burkett said his firm does not anticipate that the COVID-19 outbreak will have a major effect on the U.S. 231 reparation allocation. Ceg
