According to An Garda Siochana and the Road Safety Authority, the new speed cameras are positioned on roads where people have died.
The R108, which extends from Christchurch in Dublin to Drogheda in Co Louth, is 48km long, with 3km of one-way dual carriageway.
There are 920 listed Collision Prone Zones in Ireland and this section of the one-way R108 is not listed.
The compiling of Collision Prone Zones follows an extensive analysis that was carried out on our roads network over the last 10 years by the gardai in conjunction with the National Roads Authority, Ordnance Survey Ireland and the Local Government Computer Services Board.
During the last 10 years, the speed detection unit has operated on the one-way R108 dual carriageway on a daily basis.
It is time for the Garda Ombudsman or an independent review body headed by an engineer to examine speed limits and the siting of speed cameras in Ireland.
