Dublin Port Tunnel

The Dublin Port Tunnel (2001-2002) links Dublin Port to the national road network. It employed 5000 people over the course of its construction. At 5.6km it is the fourth longest in an urban setting in Europe. Some 1,600 metres of cut and cover, plus retained cut had to be executed at the Northern end/Whitehall, with 600 metre of cut and cover at the Southern end. Mowlen UK as part of a consortium had responsibility for this part of the project.

Second Coen Tunnel (2010-2011)

Commenced works on the above project in 2010 at Barndrecht casting yard which is located near Rotterdam.

Traditional form work was used, firstly casting the floor slab, then the central gallery. The outer walls and then the roof slab followed. Rebar detailing was typical for an immersed tube tunnel.

Four tunnel elements in all were built, each measuring 178 metres in length and 30 metres wide at a height of just over 8.5 metres.
