Over the past couple of months, the contracting joint venture has been carrying out preparatory work, clearing the roundabout of vegetation and creating a temporary road layout around the A19/A1058 Coast Road roundabout as part of the £75m scheme.
Sisk Lagan has a £40m main works contract to lower the A19 beneath the existing A1058 Coast Road and roundabout to reduce congestion on the north side of the Tyne Tunnel.
This week the main piling work started on the northern side of the roundabout which will create the start of the underpass.
As this progresses closer to the bridge that carries the A1058 Coast Road a contraflow system will be put in place on the westbound carriageway.
This piling work will form the new support for the A1058 road ahead of the underpass being dug out. By lowering the A19 beneath the existing A1058 Coast Road and roundabout this will create the third layer of the roundabout.
Highways England project manager Julie Alexander said: “This is a great milestone in the project which will see work start on creating the third layer of the roundabout. This is a complex piece of engineering which has required some careful planning and once complete will bring real benefits for drivers in the North Tyneside area and to the wider economy.”
