The Taoiseach was joined at the opening of the €250 million project by Cllr Seamus Weir, Cathaoirleach of Mayo County Council, project partners and elected representatives.

The Westport to Turlough N5 Road Project is a 25.7km roadway that comprises of 20.3km of type two dual carriageway and runs from northwest of Westport at Deerpark East to the townland of Ballyneggin near Turlough where it connects with the existing N5.

The first phase of the project, a 10km section from the N5 roundabout at Ballyneggin to Pheasant hill on the Westport Road opened to the public at the end of April 2023. The completion of this venture sees the conclusion of the largest infrastructural project ever undertaken in the county.

Consultants, Roughan & O’Donovan- AECOM Alliance, along with the Mayo County Council’s National Roads Office advanced the road project from concept up to the successful CPO & EIA process with An Bord Pleanála.

Roughan & O’Donovan were procured for the preparation of the tender documents and tendering process for the award of the Design and Build Contract. The Design and Build Contract was awarded to Wills Bam Joint Venture in November 2019 and construction on the scheme began in January 2020.

The scheme will bring a range of benefits including, the reduction of traffic congestion in Castlebar and Westport, therefore improving road safety for vulnerable road users in those areas.

It will offer improved connectivity between the towns of Castlebar, Westport and Ballina and improve the connectivity to other vital roads infrastructure such as the N59, N60 and N84 national routes.

The construction and engineering of the new Westport to Turlough N5 project saw a multiple of engineering solutions considered and planned out. 600 acres of land was acquired from 250 different landowners as part of the development.

Along with the construction of the new National Road, there were 20km of local and other roads improved and 7km of active travel roadways built. Two railway bridges, six roundabouts, 13 underpasses and 11 overbridges were also constructed to facilitate the project.

There are also several environmental benefits to this project which will enhance the environmental quality in both Castlebar and Westport with a reduction in traffic passing through them, thus improving air quality and reducing noise.

Material excavated from Drumlins during the construction period was reused within the road project, while unsuitable soft material that was excavated was set aside in adjacent environmentally controlled recovery areas.

Taoiseach, Leo Varadkar speaking at the opening ceremony said:

“The completion of the N5 Westport to Turlough Road project is a significant development for the people of County Mayo and the West, and I am honoured to open it having approved it during my first term as Taoiseach.
