Route
Ottershaw - West End
The A319 now begins at the Ottershaw roundabout with the A320. It then runs through woodland for a mile or so before emerging alongside Fairoaks Airport, a popular place for local private aircraft.
From there it runs over farmland towads Chobham, where there's a TOTSO with the B383. There's a STOP sign here due to the lack of visibility onto the main road, and the right turn you have to make coming the other way is easy to miss due to the narrow width.
Shortly after this, there's a roundabout with the A3046 and the A319 turns off to the right. It then runs for a few miles more past the Gordon Boys' School and terminates on the similarly named roundabout, meeting the A322 and B311.
