Youngsters have been given the chance to preserve the past and present for future generations.
As part of the work to create a triple decker roundabout at the Silverlink junction on the A19 and A1058 Coast Road, a time capsule containing items donated by schools and businesses will be buried on site.
Pupils at Hadrian Park Primary School are among the first to put their items in the capsule, including a video the children have produced themselves about the school and teachers.
They were joined by Mayor Norma Redfearn as they finished off their project.
Highways England assistant project manager Steven Cox said: “We have been really pleased with the contributions we have received from the wider community who have been willing to get involved in this project.
“There will be a wide range of items including pictures and videos, as well as brochures and memory sticks.
“We would like to thank everyone who has got involved and hopefully when it is dug up in 100 years it will provide a great insight into the past.
“There will be information on the £75m Highways England scheme and our contractors Sisk Lagan JV, along with photographs which show the different stages of progress on the scheme.”
Highways England is also holding a competition for schools to design and build a model school using recycled materials.
It will run from May to September, with Hadrian Park Primary School already signing up.
Judging will take place in October before crowning the winner Best School Design and Build Engineering Project 2018.
There will be an official unveiling of a plaque to commemorate the burying of the capsule in August.
