WORKS to facilitate Dunkettle becoming a free-flowing interchange step up a gear next week.
The busy interchange carries approximately 80,000 to 100,000 cars a day and connects with the M8 to Dublin, N25 to Waterford as well as the Lower Glanmire Road and N40 South Ring and is presently operating significantly above capacity and regularly suffers from severe traffic congestion at peak periods.
The project is expected to cost up to €100m.
Advance works for the interchange are continuing at Silversprings and at HSS Tool and Equipment Hire on Tivoli. A new boundary wall at HSS is under construction, set back to create the space for two inbound lanes between the existing dual carriageway and the Silversprings off slip.
Works to drainage, kerbing, and lighting will be progressed under night time working, in order to minimise disruption to traffic, with one lane being kept open inbound and outbound at all times.
The busy junction acts as one of the main arteries into the city at the Lower Glanmire Road, North Ring Road and Tivoli Docks.
Meanwhile, upgrades to the Sarsfield Roundabout to improve pedestrian and cycling facilities will see works take place next week on the eastern footpath from the Wilton Shopping centre junction towards the ESB junction. This will require the closure of the footpath for a time, with pedestrians diverted onto the western footpath.
Both daytime and nighttime working will continue over the next few weeks mainly in order to minimise disruption to commuters but also with a view to ensuring that works reach substantial completion by early December.
The right turn lane southbound from Sarsfield Road into the Wilton shopping centre will remain temporarily closed for three weeks as these works are progressed.
As reported in the Evening Echo in July, Transport Infrastructure Ireland (TII) also plans to install an Intelligent Transport System along the N40 South Ring.
The system will include closed-circuit TV coverage of the road network and provide information for permanent electronic message signs and provision of real-time journey time information for commuters using the route.
