Advanced Infrastructure Technologies Celebrates Bridge Milestone

“The SR 69 Twin Bridge is a prefabricated bridge unit [PBU] project,” Harriman said. “We had double CT girders by precasting two girders under the concrete deck and setting it on the bridge foundation one PBU at a time. Setting these units only requires a small concrete closure placement. These PBUs can be manufactured with a four-inch thick partial deck — a normal deck would be eight inches thick. That allows these even lighter units to be set in place and the deck cast on top.

Mammoet Removes Bridge in Florida

Mammoet assisted joint venture Archer Western and De Moya Group with the removal of the westbound State Road 84 bridge over I-95 in Fort Lauderdale, Florida, USA. Mammoet’s team suggested an alternative method, which was faster and avoided the risk of crews working over flowing traffic. The team proposed to remove the entire bridge in one night by using the Accelerated Bridge Construction (ABC) method.

Researchers Developing Quake-Resilient Bridges in New Zealand

Researchers in New Zealand have developed new technology that could make bridges more resilient to earthquakes. Their so-called ‘low-damage solution’ has a series of rocking bridge columns that move with seismic shocks, leaving bridges with little to no damage compared to conventional building methods…“This special steel, which is usually placed in the middle of the column, is actually working as a rubber band. So, during the earthquake this high-strength steel is actually trying to bring the pier back to the original position,” Palermo said.  “And we are actually trying to combine these resilience-solutions – seismic resilience-solutions – with accelerated bridge construction. How can we actually build bridges faster and at the same time (be) resilient? This system allows (us) to do that.”

Newman Road Project Receives Indiana Engineering Achievement Award

The stone arch bridge structure was demolished, and the design and construction teams used an accelerated bridge construction bridge-slide technique to erect and install the new bridge structure. Newman Road from SR 26 to Benson Road was completely reconstructed and widened, allowing for two-way traffic at the underpass. The existing Newman Road was lowered to allow larger, heavier trucks to travel much more safely under the railroad bridge. The intersection of SR 26 and Newman Road was converted to a dual-lane roadway, and the addition of a lighted multi-use path for pedestrians and bicyclists completed the project.

MassDOT Ready to Replace Eight Bridges in Eight Weekends

The $60-million-plus accelerated bridge project tees up another $400-million makeover next year. The removal and replacement of several Massachusetts Turnpike bridges is the kind of project that could easily take years to complete. But the Massachusetts Dept. of Transportation plans to dramatically speed up the process by replacing eight Turnpike bridges during eight weekends in a $60-million-plus project the agency has dubbed the “Acceler-8,” project.

Caltrans says innovative ‘accelerated bridge construction’ method is faster, safer

Caltrans shut down Highway 99 from 47th Avenue to the Highway 50 connector for four days starting Friday to replace the bridge deck at the 21st Avenue Undercrossing. While the project is having major traffic impacts on the Sacramento region, the agency says crews are using innovative accelerated bridge construction techniques to complete the work as quickly as possible. They said the techniques avoid extensive traffic shifts and lane reductions that could last up to six months.

Work begins on ‘really important’ project to improve I-80, I-215 east belt

Gleason said construction will be conducted nights and weekends but not during peak weekday morning and evening commute times. That means all lanes of the freeways will be open during those peak commute times, but similar lane shifts and configurations are expected at times during nights and weekends over the course of the next year. UDOT also plans to use an accelerated bridge construction practice to speed up the project’s timeline, according to Gleason. That means crews will work on new bridges alongside existing bridges in the area.

Crews Construct Bridge Offsite, Float It Into Place

The $131 million Wellsburg Bridge is the first alternative delivery project in the state of West Virginia.”We’ve had instances with accelerated bridge construction where we’ve constructed something very much closer, like immediately adjacent to the current bridge and slid it over in place, but nothing where it’s been constructed over a mile upstream and floated down in,” he said. “That’s definitely new for us.”

Full closure of I-295 Portland’s Veranda Street to occur on October weekend

This project also involves a reconfiguration of the roadways beneath the bridge to improve mobility and safety. Crews will construct the new bridge on the east side of the existing bridge and then a Self-Propelled Modular Transporter (SPMT) will be used to slide the new structure into place during the 60-hour interstate closure. This is the first time an SPMT is being used in the State of Maine. This accelerated bridge construction process will greatly reduce the length of time needed for this project, according to MDOT. That will save money and reduce traffic impacts.
