Mammoet Creates Causeway Cantilever

Southbound New Orleans Causeway Construction

Heavy-lift specialist Mammoet has transported a set of shoulder spans for a causeway construction project in Louisiana.

The outsized units were moved by self-propelled modular transporter, or SPMT, as part of construction of the southbound lanes of the New Orleans Causeway. In total, Mammoet moved 108 spans, devising a plan to use the SPMT as cantilevers and lift the spans up to 20 feet off the end of the barge.

“Counterweight was placed on the opposite side of the trailers to balance the load. This method allowed for the installation of an average of four spans, measuring approximately 17 meters in length, per day,” a spokesperson for Mammoet said.

Headquartered in Schiedam in the Netherlands, Mammoet is one of the oldest heavy-lift firms in the world and provides a range of breakbulk services from transportation and logistics to crane rental.
