What's happening near Lyneham?
 
Seen this? Off topicish, but weird.


A ripped up road could cost millions to repair after mysterious underground movements left it so warped it looks like it had been hit by an earthquake.

A section of the B4069 near Lyneham in Wiltshire has been so badly damaged the tarmac has completely snapped or is at a 45 degree angle.

Wiltshire Council say the road has been closed since February 17 - but some drivers are still trying to use it according to police.

The earthquake-like damage has been caused by unexplained underground movements which will now be investigated.

Local residents claim the subsidence has been getting worse over the last year and a landslip was inevitable.

These things aren't unheard of. The main A625 road that ran via the Hope Valley and Castleton to Chapel-en-le-Frith slid away altogether in the 1970s due to ground instability, despite repeated repair attempts. The land is still moving, even today and the road was permanently closed in 1979.

It's the new Olympics skateboard training facility.

That’s Lyneham banks and has had a subsidence issue for years given the sharp drop off on one side. They thought they’d reinforced and fixed it - apparently they haven’t!

Probably road footings damaged by the constant passing of lorries from Viridor who regularly ignore the 7.5T weight limit.

Dauntsey Bank was always a tad dodgey!

- so an Aberfan type event, where water saturated sub-soil starts to behave like a liquid - as happens with some earthquakes.

Probably not helped by the fact a large area just above the road has a) been cleared of vegetation b) Had a fairly large dwelling built on it and c) a large drive/parking area constructed. ... all of which will lead to a large amount of surface water runoff with no-where to go but down to the road edge... where it probably collected before going "under" the road .... with the effects as seen and described

I lived in Calne for 8 years and drove that way to the M4 about half the time. Always had running water on the first steep downhill left hand coming out of Lyneham (in Winter not unusual to see cars down the bank due to that). Don't recall seeing running water on the part of the road down Dauntsey bank. But it did get more and more undulating as time went on. They re-laid the top of the bank (the section that failed here) at least once in that time.

Perhaps the best option is to abandon the current road and spend the money somewhere else, after all they've managed without it for some considerable time.
I'm waiting to see who is first to say it's all down to climate change.

It's not down to climate change, it is caused by Brexit, obviously.

I blame Pritti Patel myself.........................

Probably someone took the anti gravity test vehicle for drive from the UFO space port located “not far from there “ in light years .


Some Glastonbury types , pockets filled with spice attempt to fold time and space fail due to wrong type of spice ?
