Suffolk County Council has said that Furgo Geoservices has made good progress in the first month of ground investigation for a series of new river crossings in Ipswich.
Fugro is undertaking the investigation to inform the design of the three bridges that will form the Upper Orwell Crossing.
Onshore testing undertaken so far has confirmed a significant thickness of Chalk below the site but that it is softer than expected. Offshore ground investigation has also got underway with two jack-up barges working in the channel of the River Orwell to drill boreholes to depths of up to 80m.
The council has said that the ground investigation work on site and reporting is expected to take three months to complete.
Suffolk County Council will hold a second consultation on the project later this year ahead of its application for development consent from the secretary of state for transport. The council hopes to start construction in 2020 and complete the scheme within three years.
The planned Upper Orwell Crossings
Crossing A - A new road crossing to the south of the Wet Dock Island, which would connect the east and west banks. This crossing would be for all road users, including cyclists and pedestrians.
Crossing B - A new road crossing of the New Cut, which would connect the west bank to the Wet Dock Island. This crossing would be for all road users, including cyclists and pedestrians.
Crossing C - An improved crossing over the Prince Philip Lock, which would connect the east bank to the Wet Dock Island. This crossing would be for cyclists and pedestrians only.
