Innovative warnings signs being installed along flood-ridden A1101 Welney Wash Road

Works to install innovative electronic signs on a stretch of road which often becomes impassable as a result of flooding have kicked off.

The signs are being put in place along the A1101 Welney Wash Road, which was submerged in water throughout October amid heavy rainfall.

They are being funded by the Norfolk Strategic Flooding Alliance and installed by Westcotec, and are fitted with LoRaWAN technology.

The signs will also allow Norfolk County Council to explore ways to share messages which warn drivers of flooding and road closures through social media channels and to in-vehicle satnav systems.

Cllr Graham Plant, the authority’s cabinet member for highways, infrastructure and transport, said: “Safety on our roads is our main priority.

“These innovative new signs will use cutting-edge technology and be deployed over an area spanning around 13 miles, placed strategically to give sufficient advance warning to drivers so that they can use alternative, suitable routes instead of the A1101.

“These new signs will be easy to read in tough weather conditions and will hopefully avoid vehicles becoming trapped on the flooded road as we have seen in previous years.”

The A1101 links Littleport to Wisbech and several villages in between including Welney, Upwell and Outwell.

The road is the lowest in England, rarely rising above sea level, and is prone to flooding when the Ouse Washes Flood Storage Reservoir is filled with excess water, making it impassable to all traffic.

In the past, motorists have regularly ended up stranded on the A1101 - including HGVs as diversion signs were not followed.

Cllr Chris Dawson, the county councillor for Marshland South, said: “I’m delighted that these new signs are being installed at Welney.

“I’ve personally been working to deliver improvements since before I was an elected councillor, so it’s great to see it finally come to fruition.

“It’s fantastic that we’re using the latest technology to alert motorists as quickly as possible to rising flood waters and road closures in real time, meaning that people will be able to access up to date, reliable information quickly and easily.”

The work will see eight diversion signs converted to fully electronic signs, switching on and displaying a diversion route when the road is flooded.

The installation and upgrade of all signs along the route is due to be completed by early next year.
