For some utterly inexplicable reason, the B9176 is and always has been completely out of area. Its entire length lies to the west of the A9, and as such it really should be a B8xxx.
Like the A833 from Beauly to Drumnadrochit further south, the B9176 crosses high moorland, often through trees and serves only a scattering of properties along its route. Nevertheless, it manages to provide some spectacular viewpoints across the Dornoch Firth and out into the North Sea.
On a map it seems to provide an important short cut avoiding an otherwise lengthy coastal route. However, the volume of traffic needing to use this important short cut is minuscule since the A9 was diverted across the Dornoch Firth Bridge.
The road was originally numbered B864 but was quickly upgraded to Class I status, becoming a southern extension of the A836. The road is therefore one of the few B86x numbers which was not renumbered B916x following the extension of the A9 north of Inverness in 1935.
When the A9 was rerouted across the Dornoch Firth the A836 was diverted to meet it just outside Tain. Our road was therefore downgraded and given its present, out-of-zone number.
