Mammoet chooses ABC method for bridge removal in Florida

Mammoet teams assisted with theremoval of the westbound State Road 84 bridge over I-95 in Fort Lauderdale, Florida, USA.

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, USA.

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.

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.

The bridge, weighing in at 2,385,200 pounds (1,082 metric tons) was initially set for demolition following a two-stage plan. The first stage was to demolish the south side of the bridge in place, then wait a few months to demolish the north side of the bridge, also in place – with each stage taking approximately 15 days.

Mammoet’s team suggested an alternative method, which not only expedited Archer Western’s original two-stage demolition plan, but also 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.

Using six trains of 8-line SPMTs equipped with 250 US ton (227 metric 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.

Mammoet has extensive experience in utilizing the ABC method, including setting a light rail system in Canada and the recent installation of a walkway at Seattle-Tacoma airport.
