N11 Kilpedder Interchange

Published 29th August 2022

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.
