M4 closures in December/January

There has been a bit of confusion about the impending M4 works, Kildare County Council seem to have the wrong info on their website. The NRA got in touch with us yesterday to say there'll be rolling closures from December 16th to 22nd between 10pm and 5am. The closures will be sectional so only one part of the road will be closed at a time.

M4 Signage Improvement Programme

The National Roads Authority is currently undertaking a project to improve the overhead signage on the M4 motorway. This work will consist of 20 overhead gantries to be installed at three primary locations; Mullingar, M4/M6 Junction and M4 Kildare (Between Leixlip and Maynooth).

Locations- Closures -Times

Mullingar

• Eight cantilever gantries (spanning the hard shoulder and left hand lane, not the entire motorway) will be erected at Junctions 13, 15, 16, 17 on both the Eastbound and Westbound sections of motorway for a total of eight signs.
• To facilitate the safe construction of the signage the left hand side lane only will be removed from normal operations. There is no motorway closure at these locations.

M4/M6 Junction

• One portal gantry sign and one butterfly sign will be erected in advance of the M4/M6 split. This work will impact the M4 Westbound only.
• To facilitate the safe construction of this signage the M4 motorway westbound at the approach to the M4/M6 split will be closed for one night only on December 16^th. The closure will take place during the off-peak hours and the carriageway will be reopened before the morning peak. (Exact closure hours will be announced closer to the closure date) Traffic will be directed off and back onto the motorway at clearly identified locations.
• This one night only closure is weather dependent therefore the closure is booked for December 16^th, but can occur from December 16th to December 22^nd.

M4 Kildare (Between Leixlip and Maynooth)

• There will be 5 portal gantry signs (spanning the entire carriageway) and 5 cantilever gantry signs (spanning the hard shoulder and left hand lane). These signs will be located at Junction 5, 6 and 7 Eastbound and Westbound.
• To facilitate the safe construction of the signage on the M4 Westbound and M4 Eastbound, alternate closures will be scheduled to ensure one side of the motorway will remain open at all times.
• These closures will occur during the off-peak overnight hours between December 16^th to December 22^nd and are weather dependent, therefore the expected closure details (exact times) will be confirmed closer to commencement of works. Again, these closures will impact one side of the motorway at one time only. Traffic will be directed off and back onto the motorway at clearly identified locations.
