Contractor Structural Soils is mooring two barges and platforms in the estuary from which it will drill a series of up to 22 boreholes up to 45m beneath the riverbed to provide detailed information on the geological conditions underneath the site of the bridge’s main towers.

The information gathered will be used by the companies bidding to build and operate the new crossing to help develop their plans and proposals for the final design and configuration of the bridge.

Ramboll is managing the work, which is expected to take eight weeks.

Mersey Gateway project director, Steve Nicholson, said: “The investigation works are an important part of the development of the project as the information on the condition of the rock at the location of the bridge towers will allow the bidders to develop their designs with confidence.”
