Sign at Ladner West Mainline says Active Mine. Authorized Access Only. Only drove as far as the lock blocks and looks like someone pulled one out of the way. There also appears to be a ditch of some sort later. Probably requires 4x4 HC.
Slightly degraded when compared to Ladner West Mainline. After a few hundred meters the road is completely blocked. However the road in the mine area is in pretty good shape.
