|Route outline (key)|
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 headed west through town along Victoria Street and then continued along the coast to Ardbeg. Here it stopped following the coast road, although it reached the sea again briefly at Kames Bay. From here it 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.
