World's Only Moving Mud Puddle

The solution is fairly simple. Either you move the road around it til its beyond the point of the original road, and repave that, or dig down, build an underground bridge, put the road on top of that, and let it flow through an artificially lowered canal til its past the road.

Theres another thing that can be done, if it really is coming up at an angle, you can attempt to pre-empt it and drill ahead of its path to see if you can get it to prematurely move a larger distance. The fact it moved 60 feet in a day once means its clearly got a lot of distance to cover and potential for movement.

Digging a channel down 50 feet or so, and in the direction of travel, would be the easiest way, instead of doing sheetpile walls perpendicular, use them for the sidewalls, anchor backwards into the ground a few hundred feet, and just let it erode underneath the bridge, while the bridge sits pretty on either side.

Im surprised they havent done more real geology on this, ground penetrating radar, seismography, prospective drilling.

I mean, its possible they have and just dont wanna talk about it, but still, the state or county needs to get on this.
