Storm Dennis: A1 carriageway closed between Grantham and Long Bennington
Flooding has closed part of the A1 near Grantham today (Sunday), after Storm Dennis brought heavy rain.
The A1 is closed northbound between the Valley Lane turn-off at Long Bennington and the A52 Barrowby Road slip road.
There is also congestion further south to the Melton Mowbray turn-off.
Traffic is also backing up along Barrowby Road in Grantham and further along the A52, also due to flooding, particularly around the bridge over the A1.
In a tweet, Lincolnshire Police said of the A1: "Please avoid the area if you can.
"Heavy rainfall in areas of the county has also created standing water in some areas. Please drive carefully and according to the conditions."
