For those interested, a video of trucks going over Mt Messenger in New Zealand - what rigs we use. More axles, more COE, 4 axle trailers, 4 axle trucks, B Trains, trucks from every manufacturer.
I used to go that way in the '70's, not so much these days...I go by more torturous roads on my motorcycle. The tunnel at the top used to be single lane, the north side entry was a sharp turn with no visibility - ''Sound your Horn before entering tunnel !'' it said on a sign. So you turn into the tunnel, and a truck and trailer would be coming through ! We call the grey rock Papa, it's mudstone and can be unstable...slips on Mt Messenger were common.
