Summary

Project Status: planned
Region/county: north west Wales (Gwynedd)
Start date: autumn 2018
End date: autumn 2020
Cost: £25m

Why we are doing it

The A55 is the main North Wales coastal route and is part of Euroroute E22 Trans-European Transport Network (TEN-T). It is also an important link, via county roads, for local towns and communities and provides a connection with the North - South A470 to south and central Wales.

This section of the A55 was upgraded to a dual carriageway in the late 1960’s and accordingly, does not comply with current highway standards and is prone to flooding.

We are proposing to improve the 2.2km length of the A55 between the Tai’r Meibion property and the Abergwyngregyn interchange. This will improve the safety on this section on the A55 and include drainage improvements to reduce the risk of flooding.

Current progress

We announced that the scheme would go ahead in July 2018.

Roman road closure

There will be a diversion in place for 4 months between the entrance to Tai'r Meibion and Crymlyn. The National Cycle Network 5 between Abergwyngregyn and Tal-y-Bont is also closed. Diversion signs are in place and maps are available showing alternative routes which includes routes for cyclists and pedestrians.
