These are the bridges of the River Forth, near Edinburgh.
The famous rail bridge, in the distance, used to stand alone in its glory, until they built the road bridge in the '60s. The authorities were told then that four lanes (2 north and 2 south) would not be enough for future traffic. So now they are building a second road bridge, behind me as I took this shot. They have been warned that 4 lanes (2 north and 2 south) will not be enough for future traffic . . .
