As lead consultant, Atkins is carrying out detailed design and site construction supervision to widen 23km of motorway, and upgrade seven interchanges on the existing M50 Dublin orbital ring motorway. The M50 is currently notorious for being the most traffic congested motorway in Ireland. Once the work is complete, it will ease congestion for 100,000 vehicles each day.

We suggested an alternative, more environmentally beneficial solution to the N3 interchange plan. Our approach to take the motorway over (rather than under) the railway line and canal has provided fewer impacts on the environment as well as cost and construction benefits.
