Dublin business and development impact in Dundrum
A separate point of interest in this Dublin news update is the start of enabling works at Dún Brí, the new development on the former Central Mental Hospital site in Dundrum. The project is set to deliver hundreds of affordable and social homes, with initial work focused on site preparation, utility connections and demolition.
Most construction activity is being contained within the site boundary, although construction traffic is expected to increase over time. Safety controls, road cleaning and traffic management measures are due to be introduced when required. Standard working hours are 7am to 7pm Monday to Friday, and 8am to 2pm on Saturdays.

Active travel and school route works continue
Works are also continuing under the Dún Laoghaire Central Active Travel Scheme, including activity on Glenageary Road Upper and Mounttown Road. The Dodder Greenway project at Ely’s Arch remains active, with some traffic delays likely.
Safe Routes to School schemes are progressing in Dundrum, Blackrock and other locations, with pedestrian access maintained throughout. Contractors are aiming to avoid peak commuting periods where possible.
Plan ahead before you travel
This week’s Dublin news serves as a reminder that even routine journeys may take longer than usual across parts of the county. If you are travelling through Dún Laoghaire, Blackrock, Dundrum or Kilternan, allow extra time, watch for temporary signage and follow diversion routes carefully. For anyone monitoring transport and Dublin business activity, these updates are essential for planning the week ahead.
