Cardiff Bay Barrage
Cardiff Bay Barrage

The Cardiff Bay Barrage lies across the mouth of Cardiff Bay, Wales between Queen Alexandra Dock and Penarth Head. It was one of the largest civil engineering projects in Europe during construction in the 1990s.

[edit] History

The concept of a barrage was first suggested in the 1980s as a way to help regenerate Cardiff's largely disused docklands. The barrage would create a large freshwater lake intended to attract investment into the docklands. The bay was part of the Bristol Channel which has the second largest tidal range in the world. As a result, for half of the day, the bay was empty of water, leaving large unappealing mudflats exposed. The barrage was consequently seen as central to the regeneration project. The government established the Cardiff Bay Development Corporation to build the barrage, and to redevelop the area as a whole.

[edit] Opposition

Opposition to the project came from many quarters. Some local politicians (including the area's MP, Rhodri Morgan, now First Minister of the Welsh Assembly) said the scheme would cost too much money. Local residents feared that their homes would be damaged by the permanently raised water level. Environmental groups strongly opposed construction because the bay was an important feeding ground for birds, which would be lost following impoundment.

[edit] Construction

Construction, which was undertaken by a Balfour Beatty / Costain Joint Venture[1], started in 1994, following the successful passage of the Cardiff Bay Barrage Act through the UK Parliament. The bill included provisions for compensation for any homes damaged by the barrage and a large wetland habitat for birds further east down the Bristol Channel. Features include a fish pass [1]to allow salmon to reach breeding grounds in the River Taff and three locks for maritime traffic. Construction was completed in 1999 and shortly afterwards the barrage came into effect. The impounding of the River Taff and River Ely created a 2 km² (500 acre) freshwater lake.

[edit] Today

The barrage has played an important role in the regeneration of the area. Attractions such as the Wales Millennium Centre, the National Assembly for Wales, shopping and watersports have since moved onto the waterfront. In 2000 the Cardiff Bay Development Corporation was dissolved, and the Welsh Assembly awarded a contract to Cardiff County Council to manage the barrage, as the Cardiff Harbour Authority.

One of the major selling points of the proposed development was the opening up of a new pedestrian and cycle route across the barrage. This would not only enhance tourism on both sides but provide a pleasant and safe short-cut between Cardiff and Penarth, cutting two miles off the journey otherwise taken on the heavy-traffic roads further upstream. However, this benefit has yet to materialise as there is still no public access right across the barrage. This is due to a lack of agreement between the derelict access land owners (Associated British Ports) and Cardiff Council. The "unfinished" barrage has been the cause of much embarrassment to the Welsh Assembly.[citation needed]However, the CHA have made significant progess in the creation of bay edge walkway and have redeveloped a large portion of the previously unaccesible bay periphery. It is hoped by early summer that the whole route will be open to allow public access from mermaid key to penarth marina.

The Cardiff Harbour Authority has developed a Sea Angling zone on the outer breakwater arm. Catches are good and there has been positive feedback from both local and visiting anglers. For more information visit the CHA website.

The barrage has been short listed for the British Construction Industry Award (BCIA) to find the ‘Best of the Best’ construction project over the last 20 years [2] [3].
