The bypass is expected to create a safer travel environment while also improving public transport accessibility and access to and from Sallins train station.

The new bypass comprises of approximately 1.7km of dual carriageway and 1.85km of single carriageway and includes a structure under the Dublin Cork Railway Line and bridges over the M7 at Osberstown, the Grand Canal and the River Liffey.

This is a significant infrastructure project and one that we believe will benefit the people of Kildare hugely through lower traffic volumes, improved access and a safer travel environment.

Atkins – a member of the SNC-Lavalin Group – supported Kildare County Council, the Department of Transport and Transport Infrastructure Ireland (TII) in delivering this €110m regional transport project, having been appointed to assist with the tender process, appointment of a contractor and supervision of the works undertaken by the SIAC / Colas joint venture during the design and build phase.
The new bypass comprises of approximately 1.7km of dual carriageway and 1.85km of single carriageway and includes a structure under the Dublin Cork Railway Line and bridges over the M7 at Osberstown, the Grand Canal and the River Liffey. The project also saw the construction of Active Travel infrastructure including 2.5km of shared cycle and pedestrian pathways and 2.3km of segregated cycleway and pedestrian footpaths.
The new Sallins Bypass in County Kildare, including the new Junction 9a Osberstown Interchange, is now open to traffic, providing greater accessibility to and from the M7 to Naas, Sallins and environs. This is the last major milestone in the project, which included the associated widening of the M7 motorway between junctions 8 and 11, that has provided major benefits for users of the motorway since completion.



Celina Barrett, Director of Services, Roads, Transportation and Public Safety, Kildare County Council, said: “Kildare County Council is delighted to officially open the new Sallins Bypass. I would like to congratulate all involved in the successful collaboration between the Kildare National Roads Office, Kildare County Council, the Department of Transport, Atkins and the contractor SIAC/Colas JV. This is a significant infrastructure project and one that we believe will benefit the people of Kildare hugely through lower traffic volumes, improved access and a safer travel environment. We are committed to delivering and enabling infrastructure for a connected county and this project is an important part of delivering on that commitment.”
