In 2024, England turned old fishing nets into a 16-metre footbridge; the 3.5-tonne structure needs smaller foundations and less maintenance than a conventional bridge

• The project used modular blocks, which mostly can be placed by hand, instead of traditional reinforced-concrete retaining walls.
• The blocks fit together like a Lego system, with little or no mortar needed.
• Old fishing nets seldom find a second life.
