Get the grey cells working again then!
Southampton Docks to London mid/late 70s : Past Central Station and up The Avenue, or Teboura Way and join The Avenue further up. Beware slow speed rollovers on the Chilworth roundabout. Up to the Winchester by-pass, (did we really run through Chandlers Ford?), Hockley lights, Spitfire bridge. Kings Worthy split right for A33 London rather than A34 Newbury. Up past Popham Cafe, join M3. M-way to Sunbury and onto A316. Choice of routes here, could go from Richmond (Old Deer Lorry Park) up to A205 Sth Circular, but my normal one was a left turn to go past Kew Gardens. Over Kew Bridge, rt onto A4. Past Fullers Brewery towards Earls Court. At lights turn rt back towards the river. Along the Embankment, then over Vauxhall Bridge. Elephant and Castle (lorry park there too) over Tower Bridge (Tooley St lorry park). Now by Tower of London another choice, either up to Aldgate (lorry park) and onto A13 there, or right past Royal Mint and join A13 at Limehouse. A13 is then a straight run past Isle of Dogs, Blackwall Tunnel turning, Silvertown (Tate and Lyle), inland clearance or liftoff, for Seatrain boxes at the docks there. Parking outside on old railway lines beside the Ram Tavern. Meal in Tate and Lyles canteen.
Run past turnoff for Woolwich Ferry (that`s where you come if running sth circular from Richmond). Past Ford Dagenham with a stink of paint. Past Rainham (timber dock? Frog Island??). Purfleet, Noakes Cafe and DJV Transport for backloads.
Tilbury Docks. Overnight parking inside allowed. Eat at dockies canteen and walk outside for local pubs.
