Two massive container cranes arrived at the Port of Everett on Tuesday morning to support the port’s south terminal modernization project.

The cranes left the Port of Los Angeles on May 31 after spending 10 days getting loaded on barges and prepped for the journey. Weighing 2.4 million pounds each and measuring the size of almost one football field, it took 320 tires to get the cranes on the barge.

Once underway, the Michele Foss tug trucked the cranes 1,177 nautical miles to Everett. The cranes faced 12-foot seas and 60-mile per hour winds along the journey, according to the Port of Everett.

Everett’s south terminal project will allow the city to accept heavier containers, including ones carrying oversized parts for the Boeing 777X. The project includes strengthening the dock, installing crane rail, and adding roll on/roll off cargo berthing capacity.

Construction on the dock is expected to be finished in early 2020.
