Early finish for A14 bridge lifts

Thanks to months of planning, the installation of two 1,000 tonne bridges over the A14 in Cambridgeshire over the weekend was completed a full 18 hours ahead of schedule. Dutch heavy lifting specialist Mammoet has installed a pair of 1,000-tonne bridges as part of a new improved Bar Hill junction. The A14 was closed at 9pm on Friday 14th September and was not scheduled to reopen until 6am Monday. However, smooth progress meant that Highways England was able to reopen it at noon on Sunday.

Laing O’Rourke team installs 195m-long bridge

A contracting team of Laing O’Rourke and Fulton Hogan has completed a 24-hour operation to install a 195m-long bridge built away from the site of the Darlington Upgrade project in Australia. The Ayliffes Road Bridge was moved into place using self-propelled modular transporters (SPMTs) operated by specialist Sarens. The 3,600t structure was the final – and largest – offsite-manufactured bridge on the project.

The Harbor Bridge Project reaches new milestones

The Harbor Bridge Project is making progress in big ways. According to the official Harbor Bridge Project Facebook page, after the first segment of the bridge was constructed a few weeks ago; HBP crews spent the morning moving giant pieces of the launching gantry crane along the Joe Fulton Corridor to the North Approach section of the Project. The pieces were transported with a powerful, self-propelled modular transporter. In the next few weeks, construction crews will assemble the crane on-site so that it can be used to place the 100-ton concrete segments that make up the approach and cable-stayed bridge portion of the project.

Survey gives three-month bridge project high marks

WOODSTOCK—Replacement of Bridge No. 51 over Kedron Brook on Route 4 in Woodstock began in April and was completed on June 7, five days ahead of schedule … Some of the survey-takers were amazed how smoothly and quickly the bridge project was completed. The VTrans website credits use of “Accelerated Bridge Construction.” Large portions of the bridge are actually built off-site, trucked to the site, and quickly installed using cranes.

MDOT presents final three options at Falls Bridge public meeting

Seven years after the Maine Department of Transportation tapped Falls Bridge in South Blue Hill for replacement or major repair work, the 1926 tied arch bridge is inching closer to placing hammer to steel, after MDOT, Federal Highway Administration officials, and an eight-member citizen advisory committee spent 18 months exploring design options. … If replacement is chosen, an accelerated bridge construction, where the superstructure would be built off-site and joined on-site, is an option that would detour traffic for only 50-60 days and erase the question of a temporary bridge.

In the shadow of the GWB

NJDOT’s contracted project team developed an innovative maintenance and protection of traffic (MPT) plan and used time-saving accelerated bridge construction (ABC) techniques for the $4.3 million federally funded bridge reconstruction. ABC methods incorporate combinations of innovative designs and construction techniques to minimize the amount of time traffic is disrupted during construction. Many ABC projects, including this one, incorporate prefabricated bridge components that are shipped and assembled on-site. The prefabrication significantly reduces on-site construction time, resulting in shorter traffic disruptions compared to traditional bridge construction methods.

Shortening the Long Road for West Virginia Bridge Replacements

Historically, building roads across the Mountain State has proven an arduous task. So when the West Virginia Parkways Authority undertook an ambitious 30-year deck replacement program on the West Virginia Turnpike, it looked for alternative methods to ease the pain. WVPA plans to use accelerated bridge construction (ABC) to replace decks on nearly all of the 116 bridges along the 88-mile turnpike that have been identified for replacement. Using ABC, concrete panel decks are prefabricated off site and then installed within a highly compressed schedule, saving months of onsite construction time when compared with conventional methods.

Bridge replacement work big part of $43 million in Lancaster County PennDOT projects

The three-year Rapid Bridge Replacement Project began in 2016, when the county had 133 structurally deficient bridges. That meant 18 percent of the 727 state-maintained bridges in Lancaster County were in need of replacement. So far, 20 bridges have been replaced through the Pennsylvania Department of Transportation program, and work on the other 10 is taking place this year. (Six are underway, and the final four are expected to begin within the next couple of months.)
