Llannerch Bridge - have your say

Llannerch Bridge: what should happen next?


Llannerch Bridge - a stone masonry arch bridge, being inspected by a member of staff working from suspended cherry picker van

Llannerch Bridge was a late 18th or early 19th century stone masonry bridge spanning the River Clwyd. The bridge connected the communities of Trefnant and Tremeirchion in Denbighshire. 


During flooding in January 2021 caused by Storm Christoph, a nearby oak tree collapsed into the flooded river and destroyed Llannerch Bridge as it was swept away.

Denbighshire County Council is currently looking at developing options to replace the bridge, with the following key considerations in mind:



1. The previous bridge was a Grade II listed structure. The Council will liaise with Welsh Government heritage body CADW to discuss future options for the site, as part of the planning process.


2. The course of the River Clwyd has changed significantly since the bridge was built, due to ongoing flooding events. This is part of the reason that the bridge was swept away. Natural Resources Wales will therefore form a very important part of the planning process and the Council will continue to discuss how any potential replacement for Llannerch bridge would need to be made resilient to future weather events.


3. Prior to the bridge being destroyed, the road was taking volumes of traffic which far exceeded the capacity the original road was built to cope with. The Council is aware that the route was frequently used by people wishing to access or exit the nearby A55 trunk road, especially during peak hours. The Council would like to consider whether wider works are needed on this road as part of the scheme replacement.


What do we want to know?: 


The Council would like to speak to members of the public to understand their feelings towards Llannerch Bridge before working to develop preferred options for the future of the site. 

Understanding how people feel and what they need from the area will help the Council to develop a business case and bid for funding to design, develop and implement a scheme at the Llannerch Bridge site which meets the needs of the community.

Everyone is welcome to respond, however we are particularly keen to hear from the following people:

  1. Residents of Trefnant and Tremeirchion
  2. Businesses in Trefnant and Tremeirchion
  3. The wider residential community (Denbigh, St Asaph, Bodfari etc)


We will also continue to liaise with our partners in the Emergency Services, with Natural Resources Wales, CADW and Transport for Wales as part of this process.
