It is a fact that without the the exceptional work of a few dedicated volunteers on our bridges culverts and drainage we would have no Corwen Extension.

 Here we take a look at the different bridges between  Carrog and Corwen as they were in 2007.

Bridge 29 - complete de-veging, removing all tree and ivy roots, rebuilding missing and loose brickwork under the arch through the use of temporary timber centering and timber wedges to hold the brickwork in place whilst defective areas were cut out and replaced, installation of a fibre concrete waterproofing and strengthening oversaddle, complete rebuilding and repointing of all external brickwork and both parapet upstand walls.

 

carrog bridge

The brick arches wing and parapet walls of the road bridge have now been repaired by Denbighshire Council. This operation was undertaken over two separate periods in the year. The West Elevation over three weeks starting on the 28th February and the East Elevation finishing on the 21st October. As scaffold was erected over the track a diesel loco was stabled in the siding at Carrog to release the train engine. The hacking out of the defective bricks showed that the damage was further into the arch than expected when a number of layers fell out. Replacement bricks were then mortared in and pointed including the wing walls. Weep holes have been cut in the wing-walls to relieve pressure. As trains with passengers aboard have not been allowed under the bridge in its old dangerous state, the repair to the arches had to be completed before running towards Corwen could commence.
