€1m funding for N3 Mulhuddart Interchange Upgrade

Thursday, April 19, 2012

Work on the N3 Mulhuddart Interchange Upgrade can now begin after the Department of Transport today provided €1m in funding. The upgrade will ease traffic congestion at this busy junction which provides access to the Blanchardstown Town Centre and to some of our major business parks. 

The scheme was on public display before it was approved by councillors in May 2011. This upgrade has been many years overdue and should have been done when the country was awash with money. I am pleased the new Government has provided the funding at this time.

The proposed works comprise:- 
  • Construction of a new 2-span bridge on the western side of the existing road bridge together with footpath and on-road cycle lane. 
  • Modify existing bridge to one-way traffic flow southbound. 
  • Remove existing footpath on western side of bridge to provide for right turning movements and provision of on road cycle lane on eastern side of bridge. 
  • Construction of 260m of 4m wide looped on ramp to the N3 eastbound from the new bridge. 
  • Widening of the Blanchardstown Road North, Blanchardstown Road South and Old Navan Road on approach to the interchange, and widening of the N3 westbound on/off ramps. 
  • Extension of existing bus lanes on Blanchardstown Road North and Blanchardstown Road South to the proposed signalised junction. 
  • Provision of on-road cycle lane together with pedestrian footpath and grass verge on both sides of the Old Navan Road, Blanchardstown Road North and Blanchardstown Road South. 
  • Relocation of the N3 off-ramp from Navan/Cavan to the Old Navan Road approximately 48m northwest of existing T-junction. 
  • The new junction to be signalised. Relocation of the on-ramp from the Old Navan Road to the N3 approximately 150m southeast of existing junction. 
  • Replace existing interchange roundabouts with signalised junctions incorporating advanced signaling for buses. Provision of all watermains, sewers, drainage and utility infrastructure, public lighting, signage, road lining and landscaping associated with the above works.
