The yellow gantry crane used to build the new Port Mann bridge and take down the old one will soon be gone.
Overnight, crews moved in to begin dismantling the crane, which weighs close to 720 tonnes.
The crane was used to install precast concrete deck segments on the approaches for the new Port Mann Bridge.
The gantry is being relocated to the south approach of the bridge to complete the work there.
The job will take a few weeks and should be finished by mid-June.
The work means westbound traffic may be reduced to one lane on the bridge.
Lanes closures will begin as early as 9 p.m. on most nights.
While crews are disassembling and relocating the gantry speed limits on the bridge will also be reduced to 60 km/h.
