|Route outline (key)|
The B3020 runs through the picturesque (and expensive) suburban countryside on the Surrey / Berkshire boundary.
It starts on the A30 on the northern edge of Windlesham and heads north, immediately crossing the boundary from Surrey into Berkshire. There's then a staggered junction with the A330 where the road becomes a little more built-up, before it ends in Sunninghill at a roundabout on the A329.
