On Wednesday 18 August, the final main tunnel breakthrough took place on the Dublin Port Tunnel, Eire. Contractor Nishimatsu has excavated two tunnels with a total length exceeding 4.5km over the past two years.
Road haulage groups are campaigning for the operating height of the motorway within the tunnels to be raised from 4.65m to 5m in order to accommodate large trucks. Irish Transport Minister Seamus Brennan told reporters a final decision to changes on the tunnel profile would be made in early September, along with a ruling on whether trucks higher than 5m should be banned from the State’s roads.
