During February and March another system will be installed in the Conwy Tunnels along with fire protection measures. A contraflow will operate during the work.
Speed cameras will be used in both tunnels.
The dates for the work can be found here closer to the time.
Natural Resources Wales say there is "no further immediate risk of flooding" and that the focus will now be on "supporting the communities affected" and helping the area recover.

Our thoughts are with the people who have had their homes flooded. It is a devastating experience and we are doing all we can to support them at this difficult time.
The high tides and gale force winds caused the highest tides we have seen for more than 20 years. Over the next few days the tides will not be as high and the storm surge has passed. There is no further immediate risk of flooding.
We will now focus on supporting the communities affected, the emergency services and the local authority to help the area recover.
Denbighshire County Council and Natural Resources Wales have offered reassurance to people affected by flooding in Rhyl yesterday.
We are fully aware of the traumatic experience that people are going through and would like to do our very best to offer some kind of reassurance to them.
Events like this are very rare and Thursday's sea surge was extreme. In general, the flood defences along the coast have done their job and protected the majority of our coastline. The primary sea defences worked well and a temporary patch has been done to splash the wall. It held last night and we are confident it will continue to hold.
– Rebecca Maxwell, Denbighshire County Council
In terms of security, Police will have resources in the area affected by flooding and mobile CCTV cameras will also be used as added resources.

We need to make sure that people have access to the right information, at the right time and in the right place. Those affected by flooding will now be thinking about the future and they will have a lot of questions about health and welfare issues.
We feel it's vital that we get representatives from different agencies under the same roof, to act as a 'one-stop shop' for information.
We also want to know from people about their personal circumstances, things they are short of, things they need and other information that would assist us in helping people.

There will be representatives from:

- Environmental Health
- Red Cross
Residents can access the centre until 5pm tonight and over the weekend for advice on issues such as finance and insurance, health, electrical safety and how to clean up after a flood.
A Denbighshire County Council spokesperson said: "There were no further issues of flooding to report overnight. The high tide passed at around 12.30am without any further problems.
"All those people affected by flooding have been re-housed by the Council."
