Measuring the Tunnel Part Two
It's still rainy season in the tunnel so we have had to focus on some more water clearance this week. But on a little break we took some more measurements. The lined sections of the tunnel are all exactly 4 meters tall and apart from on section 4 meters wide. The right turn in to the side tunnel is a meter wider which would confirm that something big was headed that way. The larger opening would have assisted in turning a large object.
