Traffic Wales have confirmed both lanes of the A55 have now been reopened between J22 and J23, and are expected to remain so for the Bank Holiday weekend.
But a 40mph speed limit will remain in place in both directions while the operation continues to remove fuel from the cargo ship that ran aground at Llanddulas.
Environment Agency Wales says they don't believe the cargo ship that ran aground on rocks near to Llanddulas poses a major pollution threat. Officers from the agency are patrolling beaches in the area looking for signs of pollution following the incident on Tuesday evening.
Water samples have been taken at various points around the ship to investigate the light sheen visible around the vessel.
Work to offload the remaining fuel aboard the boat is due to begin on Thursday afternoon.
The agencies working to salvage the cargo ship that ran aground near Colwyn Bay on Tuesday evening have confirmed that specialists will this afternoon begin preparatory work on the recovery of fuel from the vessel.
Gareth Pritchard from North Wales Police says that “specialists are in place and hope to start work very soon and we are asking the public to keep a safe distance from the scene.”
The coastguard, police and other agencies involved in the salvage effort are due to meet at 2pm this afternoon.
They're set to discuss the best way forward in salvaging the stricken vessel, which ran aground at Llanddulas on Tuesday night.
Although the risk to the environment is said to be 'minimal', around 40,000 litres of fuel on board may need to be pumped out before the vessel can be removed.
Following a meeting this evening the Maritime and Coastguard Agency have said they believe the fuel tanks aboard the MV Carrier to be intact, and any fuel leak is likely to have been a small amount from the engine.
Salvage experts are now drawing up plans for the recovery of the ship, though at the moment there is no timescale for the operation.
Salvage expert, John Noble says those in charge of the operation to remove the ship will not take any risks.
Teams working to remove the ship that ran aground on rocks near Llanddulas on Tuesday night will meet on Wednesday evening to organise plans to salvage the vessels. They are looking to bring in specialist equipment to remove the boat as soon as possible.
The Marine and Coastguard Agency say that "a quantity of marine gas oil has leaked from the vessel." They have confirmed that 'The Carrier' has been holed in three places on the starboard side. They say they believe that the port side remains intact, where the fuel tank is located.
Officers from the Maritime and Coastguard Agency’s Counter Pollution and Salvage branch are working with all agencies on plans to remove the fuel as soon as possible.
