The former B877 (now B875) above Ettrick Bay

The B877 crossed the Isle of Bute from Rothesay to the west coast.

It started in the centre of town, at a triple point at the north end of the High Street, which also marked the start of the A844 and A845. The road then headed west through town along Victoria Street and continued along the coast to Ardbeg. Here it stopped following the coast road, although it reached the sea again briefly at Kames Bay, and cut across on Ardbeg Road as the A844 still does today. At Kames Bay it turned inland again and headed west across the centre of the island to the west coast. The road ended on the shore of Ettrick Bay at a bridge over the Drumlachoy Burn.

The B877 number did not last long as the entire road was renumbered as a western extension of the A844 later in the 1920s. As that road also took over the B879 it gained a spur from St Colmac to Ettrick Bay. In the 1970s the spur was downgraded back to Class II status, becoming the B875, which it remains.

The 1922 MOT Road List defines this route as: Rothesay - Port Bannatyne - Etterick Bay
