Two roads in Lincolnshire have been named the most dangerous in the country, a new report has revealed.
The A155 by Revesby has been labelled as high risk by the Road Safety Foundation.
And the A18 between Laceby and Ludborough has also been highlighted.
The organisation also said that crashes cost the county £453m over three years – more than most other counties.
Caroline Moore from the Road Safety Foundation told the BBC the A18 was a particular concern.
“The A18 has come back into our list as one of the highest risk roads and over time we are seeing the accidents increase per year.
“We’ve looked at the roads before, we’ve driven down the road and it’s easy to see that the road needs really good protection for vehicles coming off the carriageway.”
The report by the Road Safety Foundation found that fatal and serious crashes on the A18 increased from ten in 2008 to 2010 to 17 in 2011 to 2013.
The stretch is rural and tree-lined as well as winding and narrow, the report notes.
It said: “These characteristics are likely to explain the high concentration of run-off crashes on the route.
“Nearly a third of crashes were at junctions.”
