|Route outline (key)|
The road starts on the A267 near Hellingley and goes south (along the pre-bypass A267) to Lower Horsebridge. At this point the B2104 forms a multiplex with the A271 heading east to cross the Cuckmere River. The B2104 regains its number at Upper Horsebridge and heads south along the pre-bypass A22 into Hailsham, where it joins the the A295 to form another multiplex through the southern part of the town centre.
The point at which the B2104 reappears is its original northern end. It leaves town along Ersham Road and winds its way vaguely in the direction of Eastbourne across a flat landscape. It goes under the A27 and into Stone Cross where it meets the B2247 (the pre-bypass A27).
Continuing south, the B2104 enters Langney and crosses the B2191 at twin roundabouts in the village centre. This was the original southern terminus of the B2104 as it ended here on the A259 but it now continues south for about another mile to conclude at the Langney Roundabout on the current route of the A259.
