The implementation of the Clare River (Claregalway) Flood Relief Scheme has been ongoing over the last three years with the works being progressed by the Office of Public Works (OPW) direct labour force.
However, in recognition of the significant flooding problems in the area it was agreed to proceed with advance interim measures to reduce flood risk and by 2012 the following remedial works were successfully completed in advance of the main scheme works:
- Construction of flood eye at Claregalway Bridge
- Construction of new bridge at Crusheeney.
