|Route outline (key)|
The B1089 is a short road in Huntingdonshire, which has moved east over the years and so is not connected to its original section.
In 1935, the A141 was diverted to run via Warboys instead of via Somersham, and the B1089 took over the A141's old route as far as Somersham, where it now ended on the B1086 on the west side of the village. This situation lasted until the building of the A141 Old Hurst bypass which led to the downgrading of the B1089 between Old Hurst and the rerouted B1040 at Pidley.
The current route of the B1089, therefore, is the truncated road, less than a mile in length, between the B1040 at Pidley and the B1086 at Somerton. A short section of the B1040 just to the west of here runs along what was the B1089 but the remainder of the road has been declassified.
