The Taoiseach, Leo Varadkar TD, officially opened the new M11 from Gorey to Enniscorthy on Thursday before a large crowd of invited guests including local politicians, chamber members, stakeholder representatives, religious representatives and workers who constructed the new roadway.
The new road is 39km in length and cost €400m to complete. The project also includes 3km of new regional road (R728) between the new Ballydawmore junction and Tomnafunshoge.
Over 1,850,000 labour hours were invested in the scheme during the construction period and the overall project includes 18 overbridges, five underbridges, 31 accommodations underpasses and three rail and river bridges.
During the initial work archaeologists from TVAS Ireland Ltd excavated over 190km of test trenches along the length of the project resulting in the discovery of 129 previously unknown archaeological sites,
The foundations of a two-room rectangular house, believed to have been built around 5,500 years ago, were uncovered in Dunsinane.
It is one of the largest neolithic houses to ever be discovered in Ireland.
It's estimated that travel time between Wexford and Dublin will be reduced by half-an-hour during peak times and 15 minutes during off-peak times as a result of the new motorway.
The overall project, which is part of the Project Ireland 2040 strategy, was initially comprised of two schemes: the Enniscorthy bypass and the Clogh to Enniscorthy scheme.
However, in 2008 the schemes were combined as the M11 Gorey to Enniscorthy motorway project.
The project was developed by the National Roads Authority - which became Transport Infrastructure Ireland (TII) and Wexford County Council.
Tramore House Regional Design office managed the scheme and Ryan Hanley WSP were the engineering consultants.
As part of the decision to make the project a PPP (Public Private Partnership) scheme the tender process began in May, 2014 with the contract being awarded to BAM Iridium in October, 2015.
The design and construction work was delivered collaboratively between BAM Civil Ltd and Dragados Ireland Ltd under an M11 Enniscorthy Joint Venture (M11 EJV) which in turn appointed Arup and RPS Group to provide the design for the project.
Barry Transportation were technical advisors to TII on the scheme.
The scheme comprises three new sections of road: the M11/N11 mainline; the N30 dual carriageway and the N30 mainline.
The M11/N11 mainline is 27km in length and connects the new Frankfort junction at the southern end of the Gorey bypass to the new Scurlocksbush roundabout on the existing N11 - around 7km south of Enniscorthy.
The N30 dual carriageway is 4km in length and connects the Scarawalsh roundabout at the eastern end to the new Ballydawmore junction on the M11 mainline.
The N30 mainline is 8km in length and connects the Scarawalsh roundabout to the new Templescoby roundabout
That section of roadway is scheduled to due to be opened to road users within the next two weeks.
