A55 Abergwyngregyn to Tai’r Meibion improvements


Start Date: March 7th | End Date: Spring 2022 

A55 junction 13 abergwyngregyn tai'r meibion

This project will improve the road's drainage system and safety on this section of the network.

For more information regarding the improvements works, please see Welsh Government links on the right, for information on traffic management see details below.

This section of the A55 was upgraded to a dual carriageway in the late 1960s and does not comply with current highway standards. The section is prone to flooding. These works will improve safety and reduce the risk of flooding.

Narrow lane deployment to facilitate the improvement works between Abergwyngregyn and Tai'r Meibion will be undertaken in both directions. 

This requires a full overnight closure to remove the existing lane lines and studs and installing new temporary markings. A full closure provides the sufficient working area to carry out the planned works and to do so safely without putting both the work force and road user at risk. Unfortunately, there are no crossovers within this location of works to complete the project with a contraflow system.

The works are being carried out overnight to minimise disruption. 


15/12/21 - 17/12/21

Overnight closure between J13 to J11 westbound for 2 nights between 21:30 - 06:00 to install a culvert.

There will be 40mph average speed control cameras when narrow lanes are in place in both directions. This is to protect motorists and the workforce who will be working closely to live traffic. We kindly ask drivers to respect our road workers, to slow down near works and obey speed limits and signs.

The cameras are operational and will be monitored closely by Go Safe.
