The Welsh Government's announced a programme to upgrade the A55.

In January a public address system will be installed in the Penmaenbach Tunnel. One lane will be closed for up to 7 days with a full Westbound closure at night.

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.
