Lego runs a website, Lego Ideas, where fans can submit ideas for new kits. People then vote on any that appeal to them; ideas that gain at least 10,000 votes are advanced to the ‘review’ stage and are considered by Lego for possible production as a set available to buy.

Fan designer MOCingbird, who is from Germany, said: “‘The World of Civil Engineering: Types of Bridges’ is the first-ever Lego Ideas submission dedicated to civil engineers, turning the spotlight on their crucial contributions to society, and highlighting the importance of bridges as a vital part of our infrastructure. With more than 50 sets having been released in Lego's popular ‘Architecture’ line, in my opinion it's about time now to pay tribute to civil engineering as well, by making the first dedicated Lego set become reality.”

The proposed kit features seven key types of bridges: tied-arch, cable-stayed, truss, cantilever (modelled under construction), beam, suspension and arch. It contains about 1,600 pieces of Lego. More details can be found on the Lego Ideas website (link opens in new tab).

The proposal for ‘The World of Civil Engineering: Types of Bridges’ went live last week and gained its first 1,000 supporters within only 70 hours, soon rising to become the fourth most popular current project on Lego Ideas.

“My submission is currently in the voting phase, aiming to gain 10,000 supporters for getting the chance of becoming a real Lego product,” said MOCingbird. “More than 1,500 votes are already in - but only if it reaches 10,000 it will advance to the review and get a chance of being produced as an official Lego set."

Previous sets that have been manufactured via the Lego Ideas route include a typewriter, a ship in a bottle, dinosaur fossils, the International Space Station and a trio of birds.

MOCingbird’s prior Ideas proposed model ‘Basement & Sewerage’ reached the goal of 10,000 supporters, thanks to support by several companies and industry associations including the Institution of Civil Engineers (ICE). But eventually another project was selected the winner by the Lego jury, said MOCingbird.
