|Route outline (key)|
The B3003 is a short B-road in west London. The road was unclassified for many years but had gained its number by the 1980s.
The road starts in the centre of Ashford (Middx) at a roundabout where it meets the B377 and B378 and heads north along Clockhouse Lane, a street name it keeps for its entire length. On the edge of town there's a bridge over the London (Waterloo) to Staines railway line, after which the road becomes semi-rural as it passes the Bedfont Lakes Country Park, so it does come as a bit of a shock to reach traffic lights giving access to a business park. There's another business park a short distance further on, after which the road ends at the signalised Clockhouse Roundabout on the A30 and A315.
