Overview of the project

Dún Laoghaire-Rathdown County Council, in conjunction with the National Transport Authority, is proposing Active Travel Improvements on Glenageary Road Upper between the Sallynoggin and Killiney Towers Roundabouts. 

Roadstone has been appointed as the main contractor for the works.

 

Scheme Details

The main works to be carried out as part of the proposed scheme include the following: 

  • Road pavement renewal works to include cold milling of the existing road for the extents of Glenageary Road Upper shown in the map above
  • The merging of the existing cycle facilities into a two way cycle facility on the north (sea) side of Glenageary Road Upper. It is also proposed to physically segregate the two way cycle facility from the vehicular lanes  
  • The left turn slip lane from Glenageary Road Upper onto Glenageary Road Lower is being removed and replaced with the two way cycle facility. Traffic counts at this junction noted that this left turn movement is low volume (1.65% of vehicles at this junction) and its removal wont impact the capacity of the junction. The existing island is being modified to provide an overrun area for larger vehicles  
  • A new toucan crossing of Glenageary Road Lower is proposed to provide a safe and segregated option for pedestrians and cyclists  
  • Side road junctions along Glenageary Road Upper are being narrowed in like with the recommendations in DMURS and additional green areas provided where possible
  • Localised repairs to the footpaths and the surface water drainage network along the route
  • A new toucan crossing is proposed at Rathdown School to cater for school children walking and cycling to the school

General Phasing of works

 

The works are to be done within the following key phases:

Note: Works will commence in Phase 2 from ‘Glenageary Park to Adelaide Road’ due to suitability

Phase 1 from Sallynoggin Roundabout to Glenageary Park.

Phase 2 from Glenageary Park to Adelaide Road.

Phase 3 from Adelaide Road to Killiney Roundabout.

Phase 4 on Glenageary Road Lower / Sallynoggin Roundabout

Phase 5 on Killiney Roundabout that cannot be completed with Phase 3

Phase 6 installation of Permanent Line marking, Cycle track and defender kerbs

(That can’t be safely installed in Phase 1 to 5)

Within each section the Westbound and Eastbound carriageways will progress separately with traffic being maintained Eastbound at all times.

The footpath and side road junctions works are to be progressed ahead of road resurfacing.

High Friction Surfacing Works will follow the resurfacing Works. A lag will be required for High Friction Surfacing works to ensure improved adhesion and these works.

 

Lane Closure and Working Time restrictions

Eastbound traffic movements with access to key destinations and houses to be maintained on the Glenageary Road Upper at all times. Work times between the hours of 08:00 and 18:00 daytime and 19:30 – 06:00 night time. 

A Lane Closure will be in place from Tuesday, 19th March 2024 to Tuesday 7th May 2024, with a one-way system being maintained 24Hrs from Sallynoggin roundabout to Killiney Towers roundabout in various phases.
