Bridge Repairs Carmarthenshire County Borough Council
Edwards Diving Services Ltd was commissioned by Carmarthenshire County Council to carry out a number of repairs to the two span masonry arch bridge, which crosses the River Teifi in Newcastle Emlyn. The bridge is a Scheduled Monument and the site is within a Site of Special Scientific Interest and a Special Conservation Area.
There were three sections to the work:
- Clearance of vegetation growth (trees) and debris to the upstream face of the structure in order to improve the water conveyance capacity of the structure
- Stone masonry repairs to the pier cutwater which had been damaged by the tree debris
- Re-pointing of the abutments on the river span with lime mortar.
All works were subject to consents from CADW and Natural Resources Wales (NRW). Further, due to the busy single lane road crossing the bridge, access to the structure for personnel and materials was only via the embankment adjacent to a private café upstream. This required advance consultation and agreements between EDS, the client and the café owners to ensure that their trade would not be adversely affected, whilst enabling access to the works.
Initially, the vegetation clearance was undertaken, including the tree trunk debris which had caused the damage to the masonry cutwater, undertaken utilising a hydraulic chainsaw. All debris had to be removed from site as it was not permitted to be stored on the banks or allowed to float downstream, in line with NRWs consent stipulations.
