The B2246 is a short B-road (though not signed as such) running through the western suburbs of Maidstone. It links the A26 at Barming to the A20 at Royal British Legion Village.
Fountain Lane starts out at a crossroads beside the former Fountain Inn (now an Indian restaurant) in Barming. The road then proceeds north for a short distance before arriving at another set of crossroads at Barming Heath, after which the road continues north as Hermitage Lane. It shortly arrives at a new set of traffic lights providing access to the Trevor Gibbens Unit, and Priority House (part of Maidstone Hospital). After the lights is the main entrance to the hospital itself on the right.
After passing the hospital, the speed limit increases from 30 to 40 mph (cut from NSL a few years ago). The road then widens and passes Hermitage Court, where there is a garden shop and not much else. It also passes a lorry site before heading over the London-Ashford railway line by Barming station. The road is now bordered by some housing on the left, though it is set back from the road. The B2246 terminates at a set of traffic lights on the A20: turn left for Aylesford, turn right for Maidstone and M20J5.
