For workers and users safety, temporary safety barriers are in place from:
- Junction 8 (Johnstown) to 2.5km after Junction 9 in the central part of the Motorway

- Junction 10 (Johnstown) to Junction 11 in the central part of the Motorway.
See detail at our Traffic Management page.
Works in progress for that specific phase are:
- Top soil stripping (removal of existing top soil)

M7 Widening Scheme
Update - September, 2018
M7 Mainline: Widening 2x2 lane to 2x3 lane
For workers and users safety, temporary safety barriers are in place from Junction 8 (Johnstown) to Junction 11 (M9 Motorway) in the central part of the Motorway.
Works in progress for that specific phase are:
Recently constructed Gantry Sign foundation in median near Junction 10
Osbertown Interchange: Built a new interchange
A new Interchange is created, earthworks are in progress in order to build new access ramps on each side of the M7 motorway
Before demolition of the existing bridge over the M7, a new junction at
Osberstown is being Constructed, requiring a new over bridge and slip roads. At
this stage median foundation works area completed, with the centre support pier
and cross heads constructed. The works for this future Bridge will require
traffic to be switched to the 2nd phase, before works can progress
at this structure. Meanwhile works continue with the proposed merge and diverge ramps at this future junction.
Sallins Bypass: Built a new 3.5km 2x1 lane road
This section will integrate 4 new bridges: including 2 over river Liffey, and one over Grand Canal. Fencing and soil striping are nearly done on this section, drainage works are in progress.
To ensure access of
heavy site engine to the construction site form Clane roundabout and minimize
traffic through Sallins, the construction of a temporary bridge over Liffey
will start soon.
