|Route outline (key)|
The B4493 is a semi-urban B-road in west Berkshire. It starts on the A417 on the southern edge of Harwell and follows Wantage Road into the village centre. The road has a width restriction; although the High Street seems plenty wide enough there is soon a sharp right-hand bend into Burr Street which could cause problems.
We soon enter open country and cross the A34 without a junction. The road merges into the suburbs of Didcot fairly soon and we enter town along Didcot Road. Presently a roundabout is reached. The town centre lies ahead but we turn left towards the station. After following Foxhall Road a further roundabout is reached where the station is to the right. We turn left and follow Station Road parallel to the Great Western Main Line to the next roundabout, where we end on the A4130.
Originally Station Road did not exist, Foxhall Road was the B4016 and the rest of the route was part of the B4007. The latter was renumbered A4130 in the late 1920s and it seems likely that the B4493 came into existence around the same time when the B4016 number was reused nearby for a more significant route.
When the A4130 gained its present route in the late 1980s the B4493 was extended in both directions giving it its current route.
