Mersey Gateway estuary investigation update
Work to investigate the structure of the bedrock under the proposed sites of the new Mersey Gateway bridge is now well underway.
Contractors working with a barge and a platform moored in the estuary are drilling a series of boreholes up to 150 feet beneath the riverbed to provide further 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.
Cllr Rob Polhill, Leader of Halton Borough Council, said: “These works are the latest step in the delivery of the Mersey Gateway Project and a visible sign for the people of Halton of the progress we are making.”
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.”
The works are expected to last until early July with teams working on barges and platforms moored on the sandbank and in the deep-water channel of the estuary.
