MEETING OF LUCAN / PALMERSTOWN / NORTH CLONDALKIN AREA COMMITTEE

MOTION NO.8

MOTION: Councillor V. Casserly

This committee calls on the manager to examine in collaboration with Fingal County Council and improved road traffic layout at the Weir Bridge to and from the direction of Laraghon to explore alternative options to traffic light system and improve ongoing movement of traffic which amounts to gridlock with the current set up

REPORT:

South Dublin County Council Traffic Section will engage with Fingal County Council to review the operation of the existing traffic signal arrangement at Weir Bridge.

Initial assessments indicate that the traffic signals are operating at or close to junction capacity. Delays currently being experienced are understood to be largely attributable to exceptional traffic volumes in the area during peak periods, rather than an operational fault with the signal system.

In reviewing the arrangement, both authorities will also have regard to road safety requirements, bridge geometry, pedestrian and cyclist movements, and the cross-boundary nature of the junction, all of which place constraints on the removal or alteration of the existing signal control.

SDCC will liaise with Fingal County Council to identify whether any operational or traffic management improvements can be made within the constraints of the existing layout.
