A 31-year-old man from Chorley was arrested on suspicion of causing death by dangerous driving. He has since been released under investigation pending further enquiries.
Following an appeal police have now identified the driver of a van who is believed to have seen the incident.
Sgt Claire Pearson, of Lancashire Police, said: “As part of our investigation we are keen to identify this driver.
“The collision happened around 8.43am and we believe the van, a Ford Transit dated from 2014, was travelling in the opposite direction.
“We are confident the driver witnessed the collision and could have some key information to assist our investigation.
“The van has a distinctive sign on the side of the vehicle and we would urge anyone who recognises the vehicle, or knows the driver, to come forward.”
A second collision happened around an hour later in queuing traffic, involving a Ford Fiesta, a Mercedes lorry, a Ford Transit van and an Audi car.
Several people were injured, including a 91-year-old woman from Orrell who died in hospital on Wednesday, January 16.
