The visits were part of National Science and Engineering Week, and were held in partnership with the Upper Forth crossing site team of Transport Scotland, Jacobs and Morgan Vinci.
Events were in Falkirk, Clackmannanshire and Fife between 10 and 26 March. More than 1,000 children from 30 primary schools had the opportunity to build a 12m cable-stay bridge.
The Bridges to Schools initiative has been running for four years in Scotland and aims to encourage interest in civil engineering among school children.
The cable stay bridge has been constructed and deconstructed by more than 10,000 Scottish schoolchildren.
The scheme, run by ICE Scotland’s Education & Careers Co-ordinator John McPartlin, has been so successful that the scheme has been taken up by the Wales and Northern Ireland branches.
