Workers at the golf club near to where five people died in a car crash say the road is notoriously bad.
Abbey, who works at Laceby Manor Golf Club, near the A18 where the crash happened, said: "The road is terrible. There are lots of accidents on it, and the speed limit needs reducing. Visibility is bad, it's notorious for crashes.
"It was a real tragedy and something needs to be done to stop it happening again."
Police have named the fifth member of the family who died in a head-on crash in Grimsby last week. She was Angela Cockburn 49 from County Durham who was killed alongside her husband, two daughters and granddaughter.
The accident happened when a car and lorry were in collision on the A18 near Laceby last week.
Police are about to close part of the A18 off again to carry out further investigation work. A number of people have been laying floral tributes at the scene of the crash where five members of the same family were killed.
