A car ran off the road and plunged into the River Welland in Spalding during the night.
Emergency services were called to London Road at about 8:50pm yesterday after reports that a blue Vauxhall Corsa had left the road and gone into the river.
A 35-year-old woman from Spalding had driven along Haverfield Road before going right across London Road and into the River Welland.
Passers-by helped the woman out of the car before she was checked over by paramedics, but she was uninjured.
No one else was involved in the accident and there was no other damage or injuries.
