Traffic Management Updates – Snugborough Interchange Upgrade

Temporary nighttime closure of section of the N3, between junction 2 and 3 | Fingal County Council

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.

Our expected timeline for completion of this scheme is 24 months. Works have already commenced on site by way of some preliminary works, site office and compound set up in Waterville Park.

Substantial traffic management will be required on the N3, Snugborough Road and surrounding road networks as works progress on site. Every effort will be made to minimise the disruption throughout the works.
