Upgrade of the R148 Leixlip to Maynooth Road

Earlier this year we began a project to reinstate the R148 roadway to its original location, with a number of significant enhancements.

By the end of 2024, the road upgrade had been substantially complete and was open to traffic with all three new signalised junctions operating.

Some works will continue through the beginning of 2025 with elements of temporary traffic management in place. These works will be mostly carried out off-line from the road and at off-peak times in order to minimise any traffic impact.

  • Footways and cycle paths will be completed along with tie-ins to the Royal Canal Greenway at the R449 and to the Intel campus at 3 locations. Vulnerable road users will benefit from enhanced safety measures including grade-separation and controlled crossing points.
  • 4 new bus stops with modern shelters will be commissioned from December 16th in convenient locations along the roadway.
  • Landscaping along the upgraded roadway has begun but it will take some time for grass and planting to be fully-established and we will continue to manage this through to Spring 2025.
  • In addition, a new section of featured planting at the R148 / R449 junction has been installed by Intel with the support and guidance of Leixlip Tidy Towns.

The opening of the upgraded R148 also brings with it a new, additional entrance to Intel which will ease traffic congestion in the area. This new entrance is located in front of the IR1 building area at the Western end of the campus and is designed to be used as the main entrance going forward.
