ABC method allows for bridge removal at a fraction of the original schedule.
Mammoet teams assisted client Archer Western and De Moya Group with the successful removal of the westbound State Road 84 bridge over I-95 in Fort Lauderdale, Florida last month.
The bridge removal is part of the I-95 Express Lanes Phase 3C project, which will result in wider travel lanes on I-95 below the interchange with I-595 and improved efficiency of the SR 84 interchange. With the removal of the westbound lane complete, crews will now work to widen the travel lanes and then reconstruct the westbound SR84 bridge.
Using six trains of 8-line SPMTs equipped with 250-ton jacks, the bridge was lifted from its abutments, traveled southbound along I-95, and finally staged on an offramp to later be demolished. This approach saved over an estimated 29 days of work.
In total, the Mammoet crew was in and out well within the allotted outage time, ensuring that the lane closures were kept to a minimum and normal traffic patterns could resume ahead of schedule.
Archer Western’s Assistant Project Manager, Massimo Raksha, stated, “As expected, Mammoet’s performance exceeded our expectations. On-time mobilization as promised with a very aggressive schedule due to the limited time between mobilization and execution (only six days), which was a huge challenge to prepare and assemble all of the equipment and systems. The team worked efficiently, was well coordinated, and never forgot that safety was job one. They had great communication and responsiveness, even while we were dealing with questions about the nature of the work.”
Mammoet has extensive experience in utilizing the ABC method, including setting up a light rail system in Canada and the recent installation of a walkway at Seattle-Tacoma airport.
