Mayo Co. Council Road Bridge Remediation 2018

Project Description

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.
