...Mr Celine has just got the get of the century, then it should be Mr Celine....
Hardly. It's a road I've driven numerous times and one I cycle on occasionally, being part of some longer loops from Celine Towers.
As soon as I saw the viaduct in the background I recognised the location, despite the changes in the tree plantations.
Opened in 1864 by the Caledonian Railway the viaduct is on a curve and has eight skewed ashlar masonry spans. In the days before computers or calculators planning and setting out the individual stones must have been a nightmare. Because of the curve on the bridge the skew increases towards the north bank of the river, so no two stones are likely to be the same.
Here's some photos of mine from 2014.
From the deck, looking up to the A72 running between the two fields, where the TOB photo was taken from -
From river level, looking downstream (east) -
Some fabulously skilled masonry -
At the east end of the viaduct the line went into a tunnel which was closed off after the line shut in the fifties. At the time I took these photos it had been unofficially reopened, but I didn't have a torch with me and due to the curve of the line continuing into the tunnel it is very dark.
It's apparently possible to cycle through it (with lights) and there are plans to surface it and make it part of the Tweed Cycleway, which is a signposted route from Biggar to Berwick.
Apologies for the thread drift, I'll post a mystery road tomorrow.
