The A893 is a trunk road connecting the A835 (which passes along the edge of the small Highland town of Ullapool) to the ferry port. The fact the road is trunk gives it unwarranted impressions of grandeur, as in fact it is only around 400 yards long.
Approaching Ullapool from the west on the A835, it turns sharp right just after passing the only filling station for miles, to avoid most of Ullapool, although in reality it is already in the urban area. Continuing ahead along the shore is the A893, otherwise known as Shore Street. The road passes shops, hotels, pubs and a number of tourist traps on its right, with Loch Broom lapping on the beach to the left. Ahead lies the pier, with Quay STreet heading right into town opposite the pier head. A short distance further on lies the entrance to the small ferry port, with the marshalling area on the right and the ferry pier to the left. This is the end of the road, although the ferry will take you to Stornoway.
Prior to the A835 being extended past Ullapool, that route ran along Shore Street to the pier. It was when it was extended around the coast to Ledmore in the late 1920s that the A893 was created to form the important, if very short, link to the pier.
