|Route outline (key)|
The B9177 is the former route of the A9 as it descends into Inverness from the south. The southern end of the route is at the Bogbain dumbbell junction, which now also provides access to the large new housing estates of Milton of Leys, developing on the hills to the south of the Highland Capital.
Heading north from the junction, the B9177 loosely follows the A9 along its eastern side until it reaches the B9006 at Cradlehall. Here, the B9006 takes over the former route of the A9 into the city centre. Originally at the sharp bend was the location of a temporary terminus for the A9 Kessock bridge approach roads, built in 1976 and remained there until circa 1978.
Previously, old stretches of the A9 from Newtonmore to Daviot had all received a consecutive series of numbers from B9150-4 (although the use of the B9151 number is speculative). Presumably these had been reserved en bloc for such use, and the council either miscounted or had not previously intended this section to carry a new Class II number. Either way the B9177 number was not the lowest available, with a number of lower numbers remaining unused.
