Dartford Crossing

you can see asda depot from the bridge, use the toll booths on the lefthand side, then leave the m25 immediately after the toll booths. follow the slip road round, and at the r/bout go straight over, down the hill, second r/bout turn eft and asda in infront of you.
i think the north bound tunnel has a limit on the left bore of about 15’62 and a 16’ limit if you use the right hand bore, but not 100% sure on that. i know when I took a DD through I had to use the right hand bore. if your over 16’ then i think its the long way round, or through the city.
