N11 Kilpedder Interchange

This new grade separated interchange on the N11 dual carriageway was required to provide access to development areas at Greystones. On and off ramps, and a vehicular underpass were constructed while maintaining uninterrupted flows on the dual carriageway.
The works included slope stabilisation, extensive new local distributor roads, a footbridge across the N11 carriageway and on-line improvements to the N11.

Waterman Moylan provided full engineering services to contractor Sisk for this design and build (D&B) project. Our team carried out two km of N11 road pavement strengthening and on-line realignment to cater for provision of a new median barrier design.
