Things are happening ...

Compare with yesterday's shot. Two cranes have been brought in. Red one on a barge from the bridge site and the yellow one on a truck. The large yellow crane is now horizontal next to the bridge (white)
The first extra is a view from Govan on the other side of the river. Compare that with the shot on the 14th and the second extra shows where the bridge will be going, hopefully tomorrow, just beyond the tall ship.
Found this video showing the view from the air
