The £75 million Triple Road Decker Project in North Tyneside is approaching its final stages. The scheme, which aims to lower the A19 under the A1058 Coast Road and Coast Road roundabout, is being delivered by the Sisk Lagan joint venture (JV).
Since the construction began in June 2016, there have been three bridges built – 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. More than 580 piles have been installed, covering seven miles from end to end, in order to support the new structure. In addition, around 80,000 m3 of soil is being removed and being used to help form the embankments on the nearby A19 Testos scheme.
“This is a busy junction used by more than 80,000 drivers every day and we have produced a video to show the incredible transformation that has already taken place. We are nearly three quarters complete now with the main bulk of the work digging out the 80,000 cubic meters of soil as the last major milestone,” said Highways England assistant project manager Steven Cox.
Over the following 10 months, improvements will be carried out to the 1,175 metres of cycleway and an extra 247 metres will be created. The gantries for improved signage will also be installed and the roundabout completely resurfaced.
“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,” said Steven Cox. “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.”
