Interim Mobility Intervention for Grangegorman Lower

Filtered permeability measures were installed on Grangegorman Lower and a filtered permeability trial commenced on the morning of 6th July 2020.

The trial includes the provision of a series of bollards and temporary planters placed on Grangegorman Lower, with appropriate signage and road markings. Dublin City Council carried out these measures in response to the recently published: “Enabling the City to Return to Work, Interim Mobility Intervention Programme for Dublin City”. For more information on this programme please visit:

Implementation of this trial results in the elimination of motorised cut-through traffic from Grangegorman Lower and drivers are no longer able to use this route as a short-cut from North Circular Road to the Quays, and vice versa. Filtered permeability through the bollards enables pedestrians and cyclists to continue to take this route. This creates a safer space for local residents and for the large numbers of pedestrians and cyclists that are expected to arrive at TUD from September 2020 and beyond. Access through the bollards is permitted for emergency vehicles.

Turning Restrictions (Except Cyclists and Access) were introduced from North Circular Road onto Grangegorman Upper and Rathdown Road, and from North Brunswick Street onto Grangegorman Lower to minimise the amount of motorised traffic entering the wider area. Motor vehicle access to any premises such as a house, business, service, school or college in the area is permitted, although some journeys are required to take a more circuitous route (via North Circular Road or North Brunswick Street) depending on which side of the bollards the premises is located. Dublin City Council’s Traffic Department has also been continuing to monitor traffic on the surrounding road network and making changes to signal times to reduce delays for all road users.

At the September 2020 Central Area Committee meeting, I secured support from my colleagues that the trial should be extended until 31st January 2021 to facilitate feedback from local residents at the January 2021 Area Committee meeting.

A report on this trial will be presented to myself and other Councillors at this meeting where we will decide on whether the filtered permeability trial should be removed, extended or made permanent.

Given that the trial has been in place for 6 months, the City Council would invite any feedback you may have at this stage to be submitted to the following email: with the title “Grangegorman Trial Feedback” preferably in the subject box. I would be grateful if you would include me in your message to the Council by emailing me at

Deadline for submissions is 1st December 2020.

Please contact me if you have any questions or queries about this initiative.
