|Route outline (key)|
The B9058 serves the northern half of Shapinsay in Orkney's northern isles. It starts on the B9059 about a mile east of the ferry pier at Balfour (although originally it was the B9058 that reached the pier; it is not known when the two numbers were swapped) and follows a generally north-easterly direction to the Ness of Ork, with the last couple of miles dead-straight.
The road is single-track throughout, getting narrower as it reaches its far end, which occurs without ceremony as the road bends sharply left. This section, ending by a picnic table on the cliff edge, was part of the B9058 until recently - but the road has now been truncated back to its 1922 northern terminus.
