A new barrier is being built on the Suffolk coast to reduce the risk of flooding from the sea near Southwold in Suffolk.
The Environment Agency is to start building an earth embankment at Easton Broad to the north of the resort.
The work, which will be carried out in stages over several years, will see a 400 metre long, 2.5 metre high bank built across the existing reed-bed.
The new bank will act as a barrier that will reduce the risk of tidal flooding to the B1127 between Reydon and Wrentham and protect the freshwater reedbeds upstream of the road during high tidal surges.
While the work is being done between late August and November, the speed limit on the B1127 near the site will be restricted to 40 miles per hour.
Mark Johnson, from the Environment Agency said: “Later this month we will build a trial part of the embankment across the reed-bed to the south of the river. Depending on the weather, the formation layer to this first section should be completed in November.
“Following this work, we will be monitoring this foundation to the embankment and continue with construction to complete the embankment over the next few years.
Easton Broad is a nationally and internationally-designated nature conservation area.
The Environment Agency says the project will specifically benefit the larger part of the habitat upstream of Potters Bridge and help keep it in a good condition for up to 50 years.
