Works near junction 23 to Llanddulas have already begun causing chaos on the A55.

Essential works on the bridge near junction 23 - which will include surface removing; waterproofing of the bridge deck; and the replacement of bridge joints - began on Monday and will effect traffic until October 18.

Road closures have already been in place since Monday and will continue while the works are going for five weeks.

Closures will continue between 8pm and 6pm until tomorrow morning with one lane west bound and a full closure east bound in place between junction 23 and junction 22 to Old Colwyn.

From today at 6pm until October 16 the entire west bound carriageway will be closed with traffic running from one lane each way on the eastern carriageway.

This will be in place from Rainbow Bridge to near junction 23. The west bound slip way at junction 23 will also be closed during this time.

Then from October 16 to 17, 8pm until 6am, one lane west bound and the entire eastern carriageway will be closed to traffic between junctions 22 and 23.

While from October 17 to 18 one lane both west and east bound between Rainbow Bridge and near junction 23 will be closed.

During all these restriction, traffic through the area will be reduced to 40mph.

The waterproofing needs to be laid in reasonable weather conditions which is why it has been programmed to take place during this period.

Similar works on the eastbound carriageway are set to take place later next year.

Transport secretary, Ken Skates, said: “We have been carrying out night time works on the Kneeshaw Lupton underbridge near Llanddulas to keep in use the temporary repairs we have previously put in place on the structure.

"We do however need to carry out permanent repairs as the bridge deck itself is now showing signs of distress. I have to reiterate this is essential work which must take place.

“I fully understand that roadworks during the daytime can cause disruption, but they need to be carried out on all major roads to ensure the safety of the travelling public and strengthen a route’s resilience.

“I ask the travelling public for their patience whilst this work is carried out and it will be on a 24 hours a day, seven days a week basis at pace so it can be completed as quickly as possible.”
