Port Mann Bridge construction crews are still unsure how long they will be off the job as a 720-tonne gantry crane remains on its side after collapsing Friday.
Investigators were onsite over the weekend but need more time to determine what caused the foot of the crane to collapse and drop a 90-tonne building slab into the Fraser River.
Work on the south approach to the bridge has resumed but the North entry will remain closed until the investigation is completed, and WorkSafe BC clears it to reopen.
"It's too early to say how long it will take to repair the gantry and if there will be an impact to the bridge construction schedule," said Max Logan with the Port Mann/Highway 1 Improvement Project.
Logan said the goal this week will be to level the gantry to its horizontal position so crews can begin repairs.
There are also plans to recover the fallen concrete slab from the river to see if it can be salvaged. If damages are too severe, Logan said a local pre-cast company will remake the block without significant delay.
An investigation will continue to assess what the crane was doing at the time of its malfunction and what its load weight was. However, reports have confirmed that the crane arm and the new deck were not damaged.
The giant crane took several weeks to be moved across the bridge last year and if major repairs are needed, the bridge's scheduled opening in December 2012 could be postponed.
