I have a question about the junction of Hwy 70 & the pipe-road at the sink-hole.

There are pipes sticking out of the ground at the junction and I've been trying to ID their purpose, all I know is that one set of them is labelled B46.

The reason for my concern is that on the second of the latest flyover video's labelled '11/14/12' you can see daylight being reflected off water on the pipe-road less than 52 meters from those exposed pipes. If the pipe-road does become submerged at that point, it will leave the gas pipes with out support and put a great deal of strain on any joints at the road junction.

Now if as I suspect those pipes are some form of 'isolator' then there may well be gas within the pipeline that is less than 50+ meters from the potential edge of the sink-hole. And if the exposed pipework goes for a SWIM then a potentially large gas leak may well ensue right next to Hwy 70 and all it would take is a spark, or possibly a hot exhaust pipe to set it off.
