Motorists in Dublin will face regular single-lane closures for northbound and southbound traffic between Loughlinstown roundabout and Cabinteely from this weekend due to work on the new N11 bus corridor and the Wyatville interchange.
The works will take place during off-peak hours until the end of January.
The northern access from Sandyford Road to Sandyford village will close temporarily from today, Friday, until Tuesday February 3rd.
The closure is to facilitate the construction of the newly realigned Sandyford Road tie-in to the existing road network. Only the southern access to the village will remain open during this period. Traffic will be diverted via Hillcrest Rd/Sandyford Road and vice versa. Local diversions will be in place close to the road closure point, according to AA Roadwatch.
On Harcourt Street in the city centre, reconstruction work is taking place on the road and footpaths, which have been extensively dug during work on the Luas project. There will be no left-hand turn into Cuffe Street during the work.
Parts of the road will be reduced to one lane. The work will commence at the Harcourt Street end and will continue towards St Stephen's Green. It will take up to four weeks to complete.
