|Route outline (key)|
The C125n is perhaps the longest C road in the country. It stretches for over 24 miles through Nithsdale, sometimes on the river bank and sometimes away in the hills to the west. The route starts on the A76 at Cadgerhall on the south side of Kirkconnel Bridge and heads south east past Kelloholm as it follows the Nith downstream. It is almost on the riverbank as it passes Sanquhar on the opposite bank, but then climbs away for a time before returning to the river at Eliock Bridge - the bridge is included as a short spur.
After several miles on the riverbank, the bridge at Glenairlie is also included as a spur, and then the road turns away from the river, passing Burnmouth as it squeezes between the hills. Keeping right at the fork at Kirkcaldy, the C125n meanders between the hills, passing scattered houses and farms until it reaches the A702 at Penpont. After crossing the Scaur Water, the road follows it downstream back to the Nith, although now running along the hillside above the river. At Cleuch, the road starts climbing again, leaving the Nith for the last time as it winds round below Blackwood Hill to find the small valley that leads to the C114n at Cairnhall. There is also one final spur, crossing Cuil Bridge, although it is not clear where it goes next.
