|Route outline (key)|
The A3003 is a link road in west London, running along the right bank of the River Thames for much of its distance.
In 1922 the A316 did not exist here as Chiswick Bridge had not yet been built, so the A3003 started on the A305 (now A205) in East Sheen where it headed north along Sheen Lane and approached the same mini-roundabout (or, rather, where it would be many years in the future) from the other direction. When the A316 was built, the A3003 was moved.
With old and new routes having converged, the A3003 now heads east along Mortlake High Street and under Barnes Bridge, by which time it is on the very bank of the Thames, before turning right at another mini-roundabout to run the length of Barnes High Street and then continuing on to end on the A306 opposite the Barnes Elms Playing Fields.
