The A3004 is a short urban A-road near Twickenham in west London.
Originally it started on the A315 in Spring Grove and ran along Linkfield Road, later moving onto the parallel St John's Road; this section is now part of an extended B363 and the A3004 currently starts on the A310 in Isleworth. It heads due east for a short distance before turning right at a mini-roundabout. (The road straight on goes to reach the bank of the Thames, where it ends on Lion Wharf.)
Now heading south, the A3004 crosses the River Crane (leaving Hounslow and entering Richmond in the process). Half a mile later it reaches a large roundabout junction with the A316; this did not exist in 1922 as Twickenham Bridge had yet to be built. The A3004 then goes over the railway line by St Margarets station and splits. St Margarets Road, to the left, is the original route; Crown Road, to the right, seems to have been added in 1935. Both branches end on the A305.
