Wednesday 15th February saw the completion of the 28m long culvert jack under Mushroom Green Embankment in Dudley. 8 nr x 110 tonne jacks pushed the specially designed culvert units and
bespoke ’tunnel’ shield mounted in front of the lead culvert which included hydraulically activated breasting plates to provide face support as well as steering jacks. The 4.2m wide x 3.0m high culverts were manufactured
in 1.5m lengths by Shay Murtagh in Northern Ireland.
