Site Investigation Works
Construction Update 17/04/2026
Ground investigation works for the Gracefield Road to Vernon Avenue Active Travel Scheme were completed in early April. Consequently, it is now necessary to carry out a permanent reinstatement on the carriageway surface at the railway bridge on Brookwood Avenue. These works are scheduled to take place on Monday 20th and Tuesday 21st April 2026, between 10am and 4pm each day. The surface course will be planed off around the slit trench locations and a new surface laid by paving machine to ensure a good finish.
At these times, traffic will be reduced to one lane at the bridge, and a stop/go system will be in place. As the works area is close to the signalised junction of Brookwood Avenue and Brookwood Rise, a traffic light switch off will be necessary during the works and this junction will also be part of the stop/go system.
Road users should expect delays in the area, especially around school closing times. Dublin City Council apologises for any inconvenience caused by these works.
The Gracefield Road to Vernon Avenue Active Travel Scheme is currently at the detailed design stage. To examine ground conditions and the location of underground utilities, Dublin City Council have appointed Causeway Geotech Ltd to carry out ground investigation works at select locations on Brookwood Avenue, Sybil Hill Road and Vernon Avenue. These works consist of slit trenches and inspection pits and are planned to take place in the week Saturday 28th March - Friday 3rd April 2026.
Lane closures and stop/go systems will be necessary to manage traffic while works are ongoing, so road users should expect delays in the area.
