A cyclist has died after a crash thought to have been caused by a pothole on a main road near Market Rasen.
The man in his early 40s had to be airlifted to hospital after the crash, which police believe was caused by a pothole on the A631 near Ash Grove Farm in North Willingham.
The cyclist, who is from the Kirton-in-Lindsey area, had been in a critical condition in the intensive care unit at Hull Royal Infirmary.
He underwent surgery on his head injuries but police have now confirmed he died yesterday, February 18.
The crash happened at about 10.50am on Tuesday, February 12.
The man had been riding with a group of other cyclists when the crash happened.
A Lincolnshire Police spokesman said: “Investigations are ongoing but clearly there is an issue surrounding a pothole in the road being a potential cause of the crash.”
Public roads are maintained by the highways department at Lincolnshire County Council - it has a statutory duty to maintain and repair the highway so it is safe for traffic.
Since the crash, Lincolnshire County Council has been made aware of the pothole and has filled it in.
Head of highways Alan Aistrup said: “Our records show that we have had no reports of potholes in that location, and the general condition of the A631 in this locality is very good.
“However, this is an on-going investigation by Lincolnshire Police and we will continue to work closely with them to assist their enquiries regarding this unfortunate incident.
“I feel it would therefore be inappropriate to comment any further at this time.”
Potholes are created by water seeping through the road surface via cracks caused by traffic. As temperatures drop the water freezes, expanding as ice, which pushes the tarmac upwards and ruptures the surface.
When the ice melts, it then leaves a void below the surface, which caves in under the stress of vehicles and forms a pothole.
Snow and ice are the worst conditions for exacerbating existing road defects.
The council relies on the public to report potholes by calling 01522 782070.
Police want to hear from anyone who saw the incident or the cyclists prior to the crash. Call investigating officer Nigel Gasgoine of the Lincolnshire Police collision investigation unit on 01522 558855. Quote incident 121 of February 12, 2013.
