This was John Green's first masonry bridge. It's a road bridge with three semi-elliptical segmented arch spans over the River Tees.
Green was the son of a carpenter. He set up an architectural practice in Newcastle in the early 1820s. His civil engineering work began with suspension bridges and he later became best known for his laminated timber bridges and viaducts.
For Blackwell Bridge, designs for a suspension bridge, an iron arch bridge and a laminated timber bridge (among others) were submitted but Green's masonry bridge was the one chosen. It's three arches measure 68ft, 78ft and 68ft, and Gatherley Moor sandstone was used. The arches incorporate cornes-de-vaches.
The bridge was widened in 1961.
