A26 road

The A26 road is primary route in the southeast of England. It carries traffic from Maidstone in Kent in a generally south-westerly direction to Tunbridge Wells and then on to Newhaven in East Sussex. It begins its journey up the Medway valley to Tonbridge; from there it crosses the Weald through Tunbridge Wells, Crowborough and Uckfield; and thence follows the River Ouse to its mouth at Newhaven, bypassing Lewes by means of a road tunnel. The road is almost entirely single carriageway resulting in congestion.
The original A26 at Lewes headed to Brighton roughly following the modern day A27 up to the mid 1950s.

The road runs for a total distance of some 50 miles and provides access to the North Kent area and its industrial base with the ferry port of Newhaven. In consequence it has a large Heavy Goods Vehicle usage.
