|Route outline (key)|
Until the roads on Cowal were upgraded, it was the B8000 that crossed the Kyles of Bute Ferry from Colintraive to Rhubadoch. The route started on the B836 near Auchenbreck and headed south, often along the shore of Loch Riddon along what is now the A886 and B866, to Colintraive Pier. Here, it crossed the ferry and continued south along the coast of the Isle of Bute to meet the A844 just outside Port Bannatyne.
The B8000 was originally unclassified but had gained its number by 1932. At that time the road ran from Auchenbreck on the then-B836 south only as far as Colintraive Pier. Mapping evidence suggests that it was extended across the Kyles of Bute Ferry to the A844 on the Isle of Bute during World War Two.
Upgrades to the roads on Cowal in the 1960s and 1970s saw our road swap numbers with the A886, so the present B8000 runs along the west coast. However, that road has been upgraded, so part of the ex-B8000 is now numbered B866, whilst the original northern end is now a forest track.
