Pupils and teachers at north-east schools have been learning from the engineers working on the A96 Aberdeen to Huntly dualling scheme.
Staff and youngsters from nine schools in Aberdeenshire were invited to a celebration event at Meldrum Academy.
It is the second year of the training programme, which has been provided by organisation Primary Engineer, to 17 schools along the route.
The initiative has been designed to encourage interest in science, technology, engineering and maths (STEM) among children.
This latest event let local school children present their projects to a judging panel from Transport Scotland and its design consultancy Amey Arup.
Michael Matheson, transport secretary, said: “As well as upgrading the A96 between Inverness and Aberdeen to dual carriageway, this government recognises the importance of benefiting the communities who live along the route as we design and build the new road.
“Our schools engagement on our major road projects, including the A96 dualling programme is leaving a legacy for the future, training teachers to deliver a programme for pupils in local schools which helps them develop an interest in the STEM subjects of science, technology, engineering and maths.
“At the celebration event at Meldrum Academy, engineers from Transport Scotland and the consultants designing the section of the road to be dualled between east of Huntly and Aberdeen took the time to offer their expertise which will help inspire the children to consider being the engineers of the future.”
