Having seen pics from the other side, it?s merely grazed it?s way in. Let some air out the tyres and reverse it out. I?m sure there is reasons why they can?t do that
Why? All you can tell from that picture is that no-one had done that (or anything else) to remove it when it was pictured.
According to the County Gazette:
Staff are letting down tyres to see if they can move the double decker coach.
THE coach has now been removed from under the bridge.
