As part of the completion of the N3 Snugborough Interchange Upgrade in Blanchardstown, southbound vehicle’s are now on the old refurbished bridge whilst northbound vehicle’s are on the new bridge.

The diversion for pedestrians to the newer bridge will remain until completion of the new signalized traffic lights to the entire junction which is due for end of June 2024. At this point the remainder of the footpaths can open to the public.

Scheme Overview

BAM Civil Ltd. are delighted to have been appointed by Fingal County Council, with co-funding from the National Transport Authority, to undertake the Snugborough Interchange Upgrade Scheme, a complex undertaking but with the goal of introducing significant improvements to the area for pedestrians, cyclists, public transport users and motorists.

This Project includes the construction of a second bridge over the N3 adjacent to the existing Snugborough Road, with new pedestrian and cyclist facilities being provided throughout, along with bus priority measures and additional lanes for turning movements.

The Snugborough Interchange is currently programmed to be completed above road level in late March.  This will facilitate traffic across the new bridge including cars, bicycles and pedestrians. The work on completing the underpasses will be the last element of the works and will be completed during April.

Substantial traffic management will be required on the Snugborough Road, Waterville Road and surrounding road networks as works progress on site. Every effort will be made to minimise the disruption throughout the works.
