The North East’s first triple decker junction in North Tyneside is entering its final stage as work starts to complete a new underpass
The £75M Highways England scheme, to lower the A19 beneath the existing A1058 Coast Road and roundabout to create the third layer of the roundabout, is now 70% complete with less than a year left on site.
Since work started in June 2016, the Sisk Lagan JV has constructed three new bridges, one to support the A1058 Coast Road over the Coast Road roundabout and two to carry the Coast Road roundabout over the newly lowered A19.
To support the new structures more than 580 piles have been installed, each 600mm in diameter and 9m deep, and 3.2km of new drainage.
Around 80,000m³ of soil, is being removed and being used to help form the embankments on the nearby A19 Testos scheme.

Highways England assistant project manager Steven Cox said: “This is a busy junction used by more than 80,000 drivers every day. We are nearly three quarters complete now with the main bulk of the work digging out the 80,000m³ of soil as the last major milestone.
“Drivers who use this junction regularly will already be able to see progress as the earth is removed to create the third layer of the junction which will mean drivers will be able to continue straight along the A19 underneath the roundabout.
“The final supports for the A1058 westbound bridge were lifted into place a few days ago and we have started the foundation work on the pedestrian and cycle bridges.”
Over the remaining ten months improvements will be carried out to the 1,175m of cycleway and an extra 247m will be created. The gantries for improved signage will be installed and the roundabout completely resurfaced.
