Dolgarrog Pipe Bridge

Over the next few months Welsh Water will be investing £1.9 million to upgrade Dolgarrog pipe bridge.

Dolgarrog pipe bridge carries two water pipes that supply homes and businesses in the Conwy Valley with drinking water.

The bridge was closed in January 2021 following significant concerns about the condition of the pipe bridge. This included the need to replace a number of the timber deck boards and also implementing additional measures to protect the high-pressure water mains.

Welsh Water has now completed a detailed design of the structure for the bridge and will be carrying out the work to refurbish and upgrade the bridge over the coming months. We will ill then work with the Conwy County Borough Council on the lighting and street furniture that may be required to enable this to become an active travel route with shared space for cyclists and pedestrians allowing easier access to Dolgarrog railway station. Network Rail and Transport for Wales are also play a role in ensuring that the new design is fit for purpose for local rail users.

The new pipe bridge is being funded by £1.2 million investment from Welsh Water and £735,000 from Conwy County Borough Council, funded by a grant from Welsh Government.

Our Plans


The work will be carried out in two phases:

Phase 1

Strengthening work on the bridge – this will need to be done when Conwy River is at its lowest level.

We plan to start this work at the end of Spring 2022 and hope to have the first phase completed in two to three months.

Phase 2

We will then carry out work to refurbish the bridge and install the new overdecking. This work should take around five months to be done.

We hope to have all the work on the bridge completed by the end of Spring 2023.

Work on site

Phase 1 of the work has started on site in May. Our contractors have created a storage and have now started on the strengthening work on the bridge.

While we carry out the work on bridge, the bridge will remain closed to the public. While we are working one of the footpaths from Dolgarrog village to the bridge has been closed to the public, however the other footpaths will remain open during the work.

We understand that our work can be inconvenient, and we would like to thank you for bearing with us while we carry out this essential work.
