A47 Lowestoft storm drain improvements
We’re carrying out work to replace a 500m section of storm drains on the A47 between Sussex Road and Lowestoft Lighthouse where there’s often local flooding. We will be working in phases to reduce the impact on the local area, and avoid the summer holidays and peak tourist season. Once complete, the road will be able to better disperse surface water and will be less prone to flooding.

Main work recommences in March 2024
In July 2023, we undertook the first phase of work, doing surveys to confirm our final drainage design, as well as inspecting and jet-cleaning existing drains, and temporarily replacing any faulty drain connections.
Prior to Christmas 2023, we started the main phase of our works, splitting it up so that other utility works could take place in Lowestoft and minimising total impacts on the public.
We will now be recommencing the main work in March 2024, continuing until June 2024.
The diagram below shows all 3 phases of work:
(There are more maps showing the work phases are available in a separate section on this webpage).

Phase 1 work, June 2023
We’re replacing a 500m section of storm drains on the A47 between Sussex Road and Lowestoft Lighthouse where local flooding can occur.
To reduce impact on the local community and avoid the summer holiday and peak tourist seasons, we will do the work in two phases.
In July, we undertook the first phase of work, doing surveys to confirm our final drainage design, as well as inspecting and jet-cleaning existing drains, and temporarily replacing any faulty drain connections.
The second phase of this work will start at the end of November 2023 for approximately four months. To make our work quicker, we will be working longer hours from 7am to 11pm (on weekdays only, weather permitting).
Phase 1
The first phase of overnight work took place between Monday 3 July and Thursday 20 July 2023 on weeknights between 8pm and 6am.
This work will involve undertaking surveys to confirm our final drainage design, as well as inspecting and jet cleaning existing drainage connections, and temporarily replacing any faulty connections ahead of phase 2.
Closures and diversions
To carry out the work safely, we will need to close the A47 between Sussex Road and Lowestoft Lighthouse. Whilst the road is closed, northbound traffic will be diverted via the A1144 and the A1117. Southbound traffic will follow the same diversion but in reverse. See diversion map below.
Phase 2Our work will stop over the summer and will start again in the autumn for approximately four months.
We expect most of this work to be carried out during the day, with some occasional overnight closures needed for certain work.Diversion map
