One of the biggest civil and infrastructural projects ever undertaken in Ireland. The M50 upgrade consisted of major road widening and improvement to the busiest road junction in Ireland. This massive project consisted of the provision of additional and auxiliary traffic lanes, the construction of numerous road and pedestrian bridges and the inclusion of twin tracks, tram stop and park and ride station for the Luas tramway. The work resulted in a significant improvement to the route capacity and traffic flow at this strategic junction with minimal disruption to existing traffic flow, adjacent residences and commercial enterprises during construction. As a major supplier Roadstone contributed to the success of this project with their unrivalled experience and commitment to quality and service.
