Oulton Road near Blundeston
The B1129 acted as a western bypass of Lowestoft, allowing traffic to pass between the A146 and A12 without going through the town.
It started on the A146 at Oulton Broad and headed north, crossing Lake Lothing and the railway line before continuing through Oulton and ending on the A12 near Blundeston.
In the 1930s, its importance merited its being upgraded to Class I status and it became the A1117.
Road improvements in the area mean that only the southernmost section of ex-B1129 is still numbered A1117; most of it is now B1375.
