The B3017 is a short link from Winkfield, through Bracknell Forest to the A332. En route, it crosses the B3034 at traffic lights near the centre of Winkfield Row before having to TOTSO right on the edge of Chavey Down. There are more traffic lights at the A329 junction before the Reading to Ascot railway line is crossed and the A332 is met at a T-junction.
The road used to continue south along Swinley Road to where it met the then-B3018 (now A322) just north of Bagshot. In 1935, this section was upgraded to a rerouted A332.
