Less than four months after PM57, Wednesday 8th November saw the second CERN's official acceptance of a lift, the PM17 one, the entry point to the HL-LHC Point 1 shaft and underground galleries, whose installation represents a major milestone for the project.

The setbacks encountered have been overcome and work will now begin in the underground galleries. As in Point 5, the installation of the utilities will take about two years, followed by work on cryogenics. By this time, the LS3 will have started and a new milestone of the project will take place: the connection of equipment in the new HL-LHC galleries to equipment in the LHC tunnel.
