Project Riverside provides the infrastructure to facilitate the transformation of an old colliery site in into a new purpose-built site for on-going housing development and community regeneration. The project was commissioned by Merthyr Tydfil County Council and part funded by the Welsh Assembly. It will be completed as a flagship venture for the Welsh Assembly to commemorate the Aberfan disaster of 1966. Tony Gee carried the project through from conceptual to detailed design, liaising with Merthyr Tydfil County Council, Network Rail and Alun Griffiths Contractors to ensure proposals were suitable, effective and favourable to all interested parties.Tony Gee provided the detailed designs for the new highway network and road bridge as well as for the new footbridge and flood defences.

We developed two value engineered solutions which provided significant benefits to the scheme. The double roundabouts originally proposed were replaced with a single roundabout. This meant the road alignment could be located further from both the river wall and the Network Rail Boundary. This also provided a reduction in the construction activities being carried out around existing live services. The single roundabout solution also removed the issue of queue stacking.

The second value engineering solution is related to the bridge foundations. There are strict regulations on the timing of construction within the region, with no construction being allowed in the river channel after the 15th October due to fish spawning in the area. Our alternative design relocated the bridge foundations and abutments from the river channel meaning construction could continue after 15th October thus providing considerable savings to cost and programme.

The below video was taken on the official opening of the bridge in December 2015.
