The B4696 is a rural road in the flat land between Swindon and the Cotswolds. It was unclassified for many years but got its number in the 2000s. The northernmost section of the road was only built in the 1970s, to serve the local industry.
The road starts on the B4042 north of - and on the opposite side of the M4 to - Royal Wootton Bassett and heads vaguely northwards. The road is largely straight and passes no places of any size: the scattered hamlet of Lydiard Plain does not really count. After a crossroads we go through a wood and then go over the railway line from Swindon to Cheltenham. A short distance further on the B4040 is crossed at traffic lights.
A few hundred yards further north we zigzag sharply left then right then bypass Ashton Keynes to the west. This village is an island in the middle of the Cotswold Water Park, a series of lakes either side of the River Thames left behind after gravel extraction. Although the lakes aren't obvious from the road we do cross the Thames and then pass the surprisingly isolated village church. A crossroads is then reached, where we TOTSO right.
Continuing east then northeast we pass more of the lakes, some of which are now visible, together with a campsite and the park visitor centre. After crossing the disused Thames & Severn Canal the road ends at a dumbbell GSJ on the A419. Cirencester is just to the left.
