The B1124 is a short link road in east Suffolk, although at one time it was much longer.
The B1124 starts on the B1123 in Holton, on the eastern edge of Halesworth, and heads roughly northeastwards. It passes several scattered houses but does not reach another village. It ends on the A145 on the southern edge of Brampton.
Originally, the B1124 continued north from here along what is now the A145 as far as Beccles, where it ended on the A146 in the centre of town. The A145 took over this section in the 1930s but was diverted east of Brampton to reach Blythburgh rather than Halesworth, leading to the stub of B1124 remaining.
