A woman has been taken to hospital with abdominal pains following a three-car collision in Northolt.
Met Police were called to the A40 Western Avenue at 8.45am, near the Target Roundabout, following a collision involving three cars.
Police said the woman, believed to be aged in her 20s, was taken to hospital by London Ambulance Service after suffering from abdominal pains.
A spokesman added that it is not thought anyone else was hurt in the accident.
The A40 Target Underpass eastbound, on the slip road from roundabout onto A40, was initially blocked but is now re-opened and traffic is said to be flowing well.
