Also called the Hertford Bridge, this overhead walkway crosses New College Lane and connects the Old and New Quadrangles of Hertford College. No waterway flows beneath it.
This "bridge" was designed by Thomas Jackson, and completed in 1914, in spite of some opposition from New College to the plan.
Like its Cambridge counterpart, this structure bears only the most superficial resemblance to the original Bridge of Sighs in Venice. Indeed, some say it looks rather more like the Rialto Bridge in that Italian city of gorgeous architecture.
