The A16 at Crowland was closed on Monday night (June 1) after another serious accident.
A Toyota Avensis and a Renault Laguna collided just before 7pm, not too far away from where Holbeach Drove pensioner Sheila Slater was killed on May 20.
A female passenger (35) in the Toyota suffered internal injuries and was taken to Peterborough City Hospital, before being later transferred to Addenbrookes in Cambridgeshire.
Police said: “Her condition is serious but stable.
“The driver of the Avensis was treated for fractured ribs and an infant escaped with no injuries. The family is from the Long Sutton area.”
The Laguna driver is believed to have escaped injury.
The road was reopened at midnight.
Police said: “Any witnesses who have not already spoken with police should call 101, quoting the incident number.”
