The Naas Ring Road project was designed to alleviate traffic from the town centre. The majority of the traffic to and from Naas town and its southern environs had previously been through Junction 9 off the M7 motorway. Our phase focused on redirecting some of this traffic by linking Millennium Park with Junction 10 on the M7 motorway at Newhall. Ultimately, the Naas Ring Road opened up large plots of serviced, industrial zoned land, adjacent the M7.
This project involved the construction of 6km of new dual carriageway, 7.3m wide on each side with a cycle way and footpath either side. The works included the re-alignment of approximately 2km of an existing road and the construction of three roundabout junctions, a signal controlled junction, two raised platform junctions and a 30m span reinforced concrete (RC) bridge over the Grand Canal. The bridge was 30m single span integral reinforced concrete, consisting of bored piles, RC abutments/wingwalls, run-on slabs, and a deck comprising pre-stressed concrete beams and in-situ slab/parapets. The finishing included aluminium parapet railings and sandstone cladding.
The services and drainage works consisted of installing foul water drainage for approximately 1.5km up to 7.0m deep, as well as 7.3km of storm drainage up to 6.0m deep. In addition, two culverts were constructed consisting of precast box culverts. Our team delivered service diversions, and the amelioration and installation of over 16km of services: gas mains, water mains, ESB ducts and telecom ducts, and the design and installation of the public lighting system. Other works included the reinstatement of hard and soft landscaping on roadside work, road markings, new signage and traffic signal works.
We coordinated power outages with ESB when carrying out bulk earthworks under high voltage OHL power lines to reduce any disruption. Temporary works were completed to realign utilities ensuring the continuity of service on Caragh road works. Detailed temporary works and water management plans reduced the risk of installing deep drainage in an area with a high water table. We also liaised with the public, local business, Kildare County Council and Naas Town Council to design and implement a successful traffic management plan.
