Duffy Crane & Hauling was contracted by Zak Dirt, Inc. for the erection of the southbound 5-span bridge of Weld County Road 53 over the North Platte River. Our 450 ton GMK6400 and 400 ton AC350-6 worked in tandem to set 150,000-pound girders, working from the river bed.

EL PASO COUNTY, Colo. - Large blocks of concrete culverts were being placed into the washed-out section of Old Pueblo Road, south of Fountain, on Tuesday.

The previous smaller, metal culvert failed during flooding after a July 23 storm. The section of road has been closed since.

A large crane lifted 10 blocks into place, each weighing 13 tons and previously acquired by El Paso County from Denver International Airport.

Workers will next backfill the area around the culverts and pave the top of it.

Officials plan to reopen the road as early as this weekend. The repair cost is $1.2 million.

Jim Reid, executive director of public works for the county, isn't bemoaning that the county doesn't qualify for federal funds to help pay for repairs.

"There's a plus and a negative to working with the Federal Emergency Management Agency," he said. "If you had FEMA here, they'd have to do all of the review, and look at and approve the plans, etc. Sometimes that can delay things up to six to eight weeks -- or six months, in some cases."

Many drivers considered the repair job too lengthy or that it went beyond what was needed, and others complained about the inconvenience of a long detour around the washout.

Yet many drivers said they approve of the repairs and were willing to wait as long as needed for them to be completed.

"I was worried about the safety," said Rex Miller, who lives near the washout. "If there had been a wreck on the Interstate, they'd like to turn (traffic) onto Old Pueblo Road. That would have been a disaster."

Two of Tatum's firefighters were injured the night of the washout when they drove into it while responding to a report of another vehicle that had done the same.

"One's in rehab and will probably be in there for another month," he said. "The other has six broken vertebrae, facial fractures and has had two surgeries so far. He'll be in a back brace for a few months."

Neighbors said they look forward to having mail delivery resume after the road reopens.

Workers overcame a high level of groundwater site, found active and abandoned utility lines and even discovered an old wooden bridge buried there.

The two white booms featured here are our National NB127 boom truck and our Terex T-560 truck crane. They are working near Denver International Airport where the US Department of Energy “Solar Decathalon” is taking place.

The Solar Decathalon is a competition featuring universities in the US, Canada and Europe. Contestants are judged on the functionality, aesthetics and efficiency of the buildings. We worked one week assembling the buildings for Hogeschool Utrecht (Netherlands) and Ecole Polytechnique Federale De Lausanne (Switzerland).

The largest crane ever used for a construction project in Summit County hoisted out the old 100-foot Nike Bridge at the Silverthorne Outlets on Wednesday to replace it with a new "Bridge to Savings."

Altogether, the town spent about $500,000 on the bridge-replacement project after determining it would be cheaper in the long run to swap out the old deteriorating bridge rather than keep up regular painting and maintenance on it, said Mark Leidal, assistant town manager.

The new bridge is made of corten steel, an alloy that forms a rust-like appearance after being exposed to the elements for several years and eliminates any need for paint.

Also, the new bridge can easily handle a 10,000-pound load, said Tom Daugherty, Silverthorne's director of public works, adding that it's strong enough "you could drive a pickup across it."

Moving the 25-year-old, 100-foot span, however, was easier said than done. The problem wasn't so much the weight of the bridges — 45,000 pounds for the old one and 52,000 pounds on the new one — a relatively light lift by modern-day standards.

Instead, it was how far the crane had to extend to safely pick the bridge up, swing it over a cluster of lodge pole pine trees and clear a handful of shops in the Outlets.

The nine-axle crane is rated to lift 450 tons, according to Frank Just of Duffy Crane and Hauling, the company that was contracted to do the work.

"Big crane," he said matter-of-factly.

All decked out with the necessary weights to counter-balance the lift, the crane weighed almost 500,000 pounds by itself.

"This machine cost $3.2 million," Just said. "It's one of the largest cranes in this area. There are a few bigger, but this is the biggest crane that's ever been in Summit County."

As the old bridge was coming up, Daugherty said the new bridge comes with at least a 50-year lifespan, and he and Leidal both took satisfaction in the fact that the bridge should outlive them.

Daugherty said the new bridge is expected to open to the public sometime at the end of next week, once the decking and concrete work is complete. After that, they'll add lighting and decorative flags.

Spanning more than 100 feet over the Blue River, the town is calling the new path a "Bridge to Savings," and it comes as a small piece of the town's downtown-redevelopment strategy. In a news release, town officials said the new bridge will provide "a beautiful new entryway" for shoppers looking to save money on their favorite brands at the Outlets.

All stores will remain open during construction, which is expected to continue through Oct. 15, and the center plans to host a "Bridge to Savings" sale in the near future to commemorate the event.
