The B2140 is a short road on the Sussex coast.
In the late 1920s, the road was extended to the coast at Rustington, then along the coast and back inland slightly to end in Littlehampton on the A259.
In 1935 the entire original section of the B2140 was upgraded to Class I status and became the A280, which it remains, except in Angmering which has been bypassed. At the same time the eastern end of the B2140 was moved to the eastern side of Angmering along what was the A259, giving the B2140 more-or-less its current route.
The present B2140 starts at a roundabout with the A259 and A280 to the southeast of Angmering and zigzags westwards through East Preston and Rustington. There are two spurs of the road off this section, which head north to the A259 and B2187 respectively.
Eventually the B2140 reaches the coast in Rustington and heads west along the sea front. When it gets to Littlehampton it zigzags inland once again, ending in the centre of town on what is now numbered B2187.
