The contractor has completed erecting the main truss! They are currently completing the final bolt torque verifications and moving the crane and crane mats off the truss.
Next, they will erect the launch truss inside the main truss. Pre-assembly of the launch truss has already begun in the mile 44 staging area.
This week, the contractor is also moving equipment to the west side of the slide using a helicopter, to prepare for erecting the receiving tower at the west abutment.
