One lane of a one-way system where a car hit a block of flats earlier today (Monday) remains closed.
The car, a Citroen C4, came off the road in Westgate, Grantham, this morning just after 10.10am and drove into the wall of a flat in Great Northern Court.
The driver was taken to Grantham Hospital suffering serious injuries. No other injuries were reported.
One lane reopened at lunch-time. Police officers remain on scene while the car is recovered.
