N3 Traffic Management Plan


N3 Traffic Management Plan N3 Traffic Management Plan

Office of Public Works (OPW)

RPS was appointed by the Office of Public Works (OPW) to prepare a Traffic Management Plan (TMP) to facilitate the construction of a 20m wide culvert crossing of the N3 dual carriageway in the north western suburbs of Dublin, as part of the Tolka River Flood Alleviation Scheme.

This scheme required extensive traffic management measures on the N3 Dublin – Cavan Road to cater for the current annual average daily traffic (AADT) of 70,000 vehicles per day at the location of the culvert crossing.

RPS produced a TMP Report and detailed plan drawings that contained traffic management measures, which were implemented to facilitate the construction of the scheme. All guidelines on speed limits, required lane widths, signs, tapers, cones, barriers and safety zones were taken from both the Irish and UK ‘Traffic Signs Manual Chapter 8’.
