At 1:50pm yesterday afternoon, emergency services were called to Leigh Road to reports of a collision between a pedestrian and a car.
Officers attended and established that a woman was crossing the road when she was involved in a collision with a Citroen Picasso that was travelling in the northbound carriageway.
The woman, who is believed to be in her 80s, was taken to hospital with serious head injuries. She sadly died some time later.
The driver of the Citroen remained at the scene to assist police with enquiries.
Road closures that were put in place at the time have since been lifted.
