Cathedral Green Footbridge, a cable stayed pedestrian swing bridge, is the centrepiece of a masterplan which has improved access routes around the Silk Mill Museum and Derwent River and reinvigorated Derby’s historic city centre.
The structure spans both the River Derwent and the adjacent Mill Race waterway, which once powered the nearby textile mill, a World Heritage status due to its role as the birthplace of the factory system where water power was first harnessed for textile production.
The bridge’s unique form incorporates a kinked backspan which links across the Mill Race and perfectly balances the main deck, which spans the Derwent. This near-effortless mechanical solution allows the bridge to rotate using minimal energy.
With just three slender cables carrying load back to a 20m high needle-like mast, the bridge swings off the river, under flood conditions, folding back into the newly constructed waterfront to Cathedral Green and enabling access to the riverside walkway whether the bridge is open or closed.
Keeping the structure as lean as possible reduced the use of materials, all of which were sourced and fabricated within 15 miles of site.
