A scheme to raise awareness of civil engineering has been running this week in Aberdeen's primary and secondary schools.
The Bridges to Schools initiative, promoted by the Institution of Civil Engineers, aims to give pupils an insight into the challenges of civil engineering while having some fun along the way.
The project has already visited Highland and Aberdeenshire, marking the 250th anniversary of the birth of Thomas Telford (left), who built hundreds of roads and bridges in the Highlands and was the first president of the Institution of Civil Engineers.
At the event, children helped construct an 8 metre-span cable-stayed bridge, using a kit supplied by the organisers and supervised by volunteer civil engineers. Once constructed, the pupils walked across the bridge to show its strength.
