Two people are in hospital following a two-vehicle crash on the Porthmadog bypass.
A van driver was seriously injured in the collision with a HGV lorry on the A487 between Porthmadog and Penrhyndeudraeth at just before 9am on Tuesday morning (26th March).
The driver was cut free and airlifted to a specialist trauma unit at the Royal Stoke University Hospital.
The driver of the HGV was taken by ambulance to Ysbyty Gwynedd in Bangor with what are believed to be minor injuries.
The road was closed for seven hours while a special crane was brought in to recover the HGV. Police urged drivers to find alternative routes in the area.
An investigation into the crash is now underway and road traffic officers are appealing for witnesses to come forward.
Sergeant Raymond Williams from the Western Roads Policing Unit said officers are ”particularly keen on speaking to anybody who may have seen the van, which was travelling from the roundabout by the fire station in Porthmadog onto the bypass towards Penrhyndeudraeth, being driven prior to the collision.”
”I am also urging anybody who may have been travelling along the A487 and who may have dash cam footage that could assist the investigation to come forward.”
Anyone with information should contact the Roads Policing Unit on 101, quoting reference no. X040474.
