Highways England has started main construction work on the £75m triple decker roundabout in North Tyneside.
This week the main piling work started on the northern side of the roundabout to create the start of the underpass.

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 wide economy.’
Ms Alexander said Highways England was aware of ‘issues’ drivers were having with increased traffic around Hadrian’s Park and was working closely with North Tyneside Council to address this.
The 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 said over the past couple of months its contractors have been carrying out preparatory work such as clearing the roundabout of vegetation and creating a temporary road layout around the A19 Coast Road roundabout.
Traffic is already using the new layout on the northern side of the roundabout, which has to be in place so the workforce can work safely, and will start using the new layout on the southern side after Christmas.
