|Route outline (key)|
The B3000 is a short rural B-road near Guildford. It is partly used as a way to access the westbound A31 from the northbound A3 (or vice versa), as the main junction with those roads is limited access. Indeed, the second half of this route is signposted "(A31)" or "(A3)".
The route starts on the A3100 (the original route of the A3, explaining why the road is out-of-zone) just south of Peasmarsh. From here it heads west, crossing the railway near Farncombe station, and heads around the back of the village and up to Compton. There's then a junction with the A3 and a sort of multiplex as it carries the southbound exit traffic for the latter road up to the next roundabout. This section was originally numbered B3000 but was taken over by the A3 when the Guildford bypass was built. Later still, when the A3 was dualled, it returned to being the B3000.
After crossing the A3 at a dumbbell GSJ (with the southbound offslip we've already met missing), the B3000 goes round Puttenham Golf Club and then climbs up the hill to meet the A31 at a grade-separated junction on top of the Hog's Back.
