Crews pushed three massive precast concrete boxes into place with hydraulic jacks underneath an active highway in Brevard County, Fla., during the week of March 29 as part of the $4-billion Brightline high-speed rail program that will extend the line to Orlando from Miami and West Palm Beach.
Innovative box-jacking method from an Italian engineering firm is deployed for the first time in the U.S. for LIRR's grade-crossing elimination project.
