MAJOR works to upgrade the traffic-choked Dunkettle Interchange have encountered difficulties after the project team revealed ground conditions in the area were “challenging”.

With ground investigation works continuing throughout the site ahead of a €100m upgrade, the team revealed that it has encountered silt deposits over 200 feet deep in a number of areas.

Works to facilitate Dunkettle becoming a free-flowing interchange stepped up a gear in recent weeks.

The busy interchange carries 80,000 to 100,000 cars a day and acts as a main junction serving arteries into the city.

At present, the interchange is operating significantly above capacity and regularly suffers from severe traffic congestion at peak periods.

The project team revealed that resurfacing works at Silversprings will recommence under night-time working from today, with footpath construction and road resurfacing planned.

The resurfacing works at Silversprings are expected to be completed on or before Friday, February 1. The Jack Lynch Tunnel will be closed at night tomorrow, Wednesday and Thursday to facilitate later start times for construction work.

Silversprings works remain on track for overall completion by mid-February 2019.

Construction of site access points will also continue over the coming period.

Over the coming week works will continue at the new access point near Burys Bridge slip road and works will get underway at the new access point from the Dunkettle local road, south of the Gaelscoil entrance.

They said that no significant disruptions to traffic anticipated over the coming period.

Meanwhile, planning works are already underway to improve capacity at the Little Island interchange with main construction scheduled to get underway on Monday, February 11.

Proposed traffic management measures are currently being planned with details expected before construction commences.

The works at Little Island Interchange are scheduled for completion by June 2019.

Work will also get underway at the N28 at Shannonpark near the Raffeen Junction on February 11 to improve traffic flow.

MEIC Ltd have been appointed to carry out the works which are scheduled for completion by June 2019.

The upgrade to the Sarsfield Road area, meanwhile, is near completion with general site tidy up works scheduled over the coming days.

No further traffic disruption anticipated here as a result of the minor remaining works.

As reported in the Evening Echo in July 2018, 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.

Silversprings works remain on track for overall completion by mid-February 2019.
