|Route outline (key)|
The A1189 forms part of the original Ipswich eastern bypass.
The road starts at what used to be a double roundabout where it meets the A1214 northern bypass and the A1071 from the town centre. It then heads south along Heath Road past the hospital, where there is a brief section of dual-carriageway. The road narrows again as it meets a corner of Rushmere Heath, after which an unclassified road crosses at a roundabout. On the far side the road is largely straight and residential before we meet the A1156 at the next roundabout.
There is a multiplex east out of town along the A1156 for over half a mile, which ends at a roundabout by Sainsbury's. The A1189 regains its number and heads south, passing under the Felixstowe Branch Line immediately, then skirts an industrial estate, accessing it via a couple of roundabouts. The A14 is soon met and the A1189 ends at its J57, which is a dumbbell interchange.
The northern section of the A1189 (between the A1214 and A1156) was constructed in the 1930s as part of a three-sided bypass (with the southern side missing, as it still is) and opened with the A1114 number. For many years this road linked the A12 and A45, with the former following the northern bypass and the latter running through the town centre. It was not until the 1970s that the A45 was taken out of the centre of Ipswich and rerouted along the whole of the A1114 before multiplexing along the A12.
The southern section of the road is later. Although the dumbbell interchange was built at the same time as the main road it served an unclassified road between Ipswich and Nacton. The A1189 was extended south along new-build and this unclassified road in about equal measures to meet the bypass a few years later.
