Helsinki’s new Kruunuvuori (Kruunuvuorensilta) bridge — 1,191 m long, car-free and built for pedestrians, cyclists and a future tram — opened April 18, 2026 with a 200‑year design life; it cuts a key route from ~11 km to ~5.5 km, saw 50,000+ visitors on opening weekend, and is part of the €326m Crown Bridges light-rail project (tram service due 2027). The project reduced embodied emissions via low‑emission materials and renewables but still has an estimated 129,000 tCO2e footprint over 50 years, highlighting why durability and modal shift matter for net climate benefit.
If the UK wants a clear target: build resilient, car‑free multimodal links that prioritise walking, cycling and high-capacity light rail; design for multi‑century lifespan to amortise embodied carbon; and pair projects with Vision Zero street redesign, lower local speed limits and strong public‑transport integration to deliver safer, greener urban growth.
