Work has begun on a new roundabout on the site of one of the worst accident blackspots in the East of England.
The £1.5m project will see a new roundabout built on the A140 at Pulham Market crossroads in Norfolk.
The site on the Norwich to Ipswich road has seen 31 people injured in 18 accidents over the past ten years.
A temporary 30mph speed limit will be in force and temporary traffic signals will be in use during off-peak periods. The work is due to last six months.
Adrian Gunson, Norfolk County Council cabinet member for planning and transportation, said: "I am delighted that work is about to start on this notoriously difficult junction.
"It has a long record of accidents, and while the measures already taken have probably reduced the number and severity of crashes, road users are still faced with having to cross or join heavy flows of high-speed traffic on the A140.
"This is when people are most at risk of being seriously injured or killed, and the roundabout will address that problem."
