Grandma and Grandpa were caught in this back-up. They thought everyone was heading for Stonehenge when, in fact, very few were. The road is a main route to other destinations and at the tiop of the hill, it narrows from four lanes to two. Hence, the back-up.
A tenon on top of an upright stone. The upright would be cut to produce the tenon and the tenons were fit into the horizontal piece where a hole, called a mortice hole, had been hollowed out. This was one way to keep the horizontal lintels in place.
These were flying over Stonehenge when we were there. An employee told me that the museum, which contains some fragile, ancient relics, has written the MoD to ask them to stop, as those relics are being damaged by the vibrations.
