X3 travels to Portishead via Martcombe, Sheepway and the marina
X4 travels to Portishead via Pill Easton in Gordano, Sheepway and Bristol Road.
X3a travels to Portishead via Pill, E-I-G, Sheepway and the marina, mornings and evenings.
All three buses meet at Combe Road and then do the Redcliffe Bay loop, via Avon Way, Down Road, Nore Road and West Hill before returning to Combe road. Quite who thought it was a good idea to only run in one clockwise direction around the loop. One needs to know the geopgraphy, as Combe Road is almost at sea level while the loop runs up steep Avon way to reach 350 feet ASL by the Highdown Schools/Old radio station site at Merlin Park, and then gently descends along the second half of Down Road and Nore Road to the bottom of West Hill at about 100 feet ASL
X5 is also running through Sheepway between Portishead and Cribbs causeway/WSM instead of the Portbury hundred bypass.
Just to add to the bizarreness, can there be anywhere else in the country, where the main street of the Town, (called High St) is below sea level and the highest part of the town at 350 feet ASL is called Down Road.

Part of Down Road is called Lower Down Road where buses don't go. A visiting friend asked me one day if there was a Higher Up Road as well !
