The concession contract between Transport Infrastructure Ireland (TII) and a consortium involving Iridium and BAM PPP was executed in October 2015 and has an operational period of 25 years. The contract comprises project design, finance, construction, maintenance and partial operation of the new infrastructure on different sections of the M-11, N-80 and N-30. The section of the N-30 state highway will be delivered to local authorities for maintenance and operation and is expected to open in four months. The works performed by the Dragados and BAM Civil joint venture took place over 45 months and required an investment of Euros 282 million.
The construction works on the 42km of new route and seven new links involved 6 million cubic meters of earthworks and the building of 98 structures including bridges, underpasses and drainage works. One of these structures was the 158-meter long bridge over the Slaney river, which has a 70 meter central span and steel beams weighing more than 1,000 tons that were manufactured in Spain.
The Iridium and BAM Civil joint venture will be entirely responsible for the route's operation.
