Riverbank stabilisation complete

Work to stabilise the bank of the River Stour in Sturminster Newton is complete.

The bank of the river, bordering the A357, was slipping into the river so, to stop any further movement and protect the busy road, it has been strengthened by Dorset Council.

Just under 500 nails, between 8 metres and 12 metres long, were drilled through the bank to secure it to the bedrock to stabilise the embankment. Steel mesh was pinned in place, followed by protective matting and finally wildflower seeds were sown.

A drilling method was used, rather than piling, to minimise vibration. This was monitored throughout the work.

The final part of the work, which reinstated the footway bordering the road and installation of the rail fence, has now taken place.

Councillor Ray Bryan, Portfolio Holder for Highways, Travel and Environment, said: “Many thanks to local residents, motorists and the town council for your positive support and understanding throughout these essential stabilisation works. 

“Our team, and our contactors Heidelberg, worked in some challenging conditions, including heavy rainfall that caused higher than normal river levels. They have done a fantastic job that has created a safer place for all.”

During the works, the eastbound lane of the A357 was closed with traffic signals in place to maintain traffic flow both ways.

Dorset Council worked closely with the town council, local ward member and those directly affected by the works before and during the works to ensure the stabilisation and the traffic management went smoothly.

Cllr Carole Jones, ward member for Sturminster Newton, said: “The workforce on site have been fantastic – many a morning they were there from 7.30am, not leaving until almost dark. It really is so wonderful not to see the awful blue and red plastic railings anymore and I would like to thank all of the residents of Stur for their patience – we got there!"

Following an arrangement with the town council, trees will be replanted on land just to the east of the town bridge.
