The Old Bridgewater Bridge demolition project involved the careful dismantling of the 1946 structure (after the new bridge opened in mid-2025) to improve River Derwent access, remove an unsafe asset, and salvage materials, with work involving land/marine operations, large cranes, and strict environmental controls, aiming to clear the way for better river flow and recreation by mid-2026.
