This project involves the reconstruction of 3 road bridges on Regional Roads in Co. Mayo. These included Kilmannin, Moyview and Ferrew Bridges. Ferrew Bridge was done over Cloonaghmore River outside Mowgownagh – 12m. Kilmannin Bridge was done over Dalgan River outside Ballyhaunis – 20m. Moyview Bridge was done over part of the River Moy in Foxford.
The scope of the project included:
The installation of precast concrete piles on the bank of the existing stream which did not impact the flow, flora, fauna, or the river stream/bed.
A headstock beam constructed over the precast concrete piles, again preventing instream working as required by Inland Fisheries Ireland.
Precast curved units were designed and made off-site (to the shape of the existing arch bridge structure) and lifted into position and placed within preformed rebates with the headstock beam.
This allowed the parapet walls to be constructed and backfilling to take place, and the roadworks to be completed, all again without impacting the river flow or riverbed conditions.
