Flood barrier at Welney Wash Road work timings

Closes 30 Sep 2020

Opened 12 Mar 2020


We are the authority responsible for the safety of reservoirs and the Ouse Washes is one of them. As part of the bank works we are doing within the Reservoirs Act we need to provide a more robust barrier on the Welney Wash Road, when needed. We have sourced a demountable barrier option that will provide the robust flood protection solution and will be bespoke to Welney.

More Information

The Welney Wash Road crosses the Ouse Washes Flood Storage Reservoir and creates a low point in the Middle Level Barrier Bank. This low point increases the flood risk to the local community and the chance of a breach in the bank if water levels were to overtop it.
When the Washes is flooded and the water level at Welney reaches a predetermined level, Norfolk County Council highways team closes the road.

We are asking for your views on when to close the road to build a concrete foundation slab across the Welney Wash Road. This work will allow us to install the demountable flood barrier in, if needed, to help protect the communities from any water spilling from the Ouse Washes.

Please be mindful this barrier (see below schematic) will be installed across the Welney Wash Road only when the Ouse Washes flood and the water level at Welney reaches a predetermined level.  When the Ouse Washes flood the Welney Wash Road is and will  remain impassable to traffic. This is a flood barrier that will protect against any water spilling from the washes and becoming a flood threat to the village.  

We appreciate that closing the Welney Wash Road will have considerable impact to the local community. We want to reduce that impact as much as possible by working with you to identify the most appropriate time of year to close the road for the construction works. There are times of the year when we are unable to carry out this work, due to bird overwintering and breeding on the Washes (November to March).

We expect that the total construction time will be 14 weeks. Out of these 14 weeks, we will need to close the road for 6-8 weeks.

More Information

A road closure is necessary due to the excavation depth and the number of services buried under the road. We need to build the formwork/temporary mould, install the reinforcement, cast the concrete and wait for it to set which can take up to 28 days. We will need all the available road space to do this.

Why We Are Consulting

To ask the communities affected by the road closure for their preferred option on the best time to close the Welney Wash Road for a few weeks.
