The Snugborough Interchange Upgrade Scheme is located at junction 2 on the N3 and Snugborough Road crossroads. It is a strategic interchange which serves Dublin 15. Blanchardstown Village, Blanchardstown Town Centre, and the Dublin Enterprise Zone, north of the N3 at Ballycdolin which supports 34,600 jobs.
The bridge will be helpful in the incorporation of the key N3 crossing element of the Blanchardstown to City Centre Core Bus Route 5. It will improve traffic capacity through the interchange from all approaches. It will allow improved traffic management of road/motorway network due to modified traffic signals and CCTV.
