Architecture, archaeology and continuing use
A tooled segmental arch ring defines the main span, with matching masonry around narrow side openings. Rubble parapets and a compact three-opening profile respond to both river flow and industrial water management.
Its story
Built in the early nineteenth century, the bridge served movement toward the station and industrial ground. Its southern side arch crossed a lade linked with riverside working sites.
Why it is included
Category B listing recognises a well-preserved transport structure whose multiple openings reveal adaptation to floodwater and managed watercourses.
What to notice
- The broad central segmental arch.
- Two narrow flood openings.
