Hertford Bridge is often called the Bridge of Sighs because of the similarity to the famous bridge in Venice. Actually, it looks more like the Rialto Bridge, and this Oxford structure was never intended to be a replica of any existing bridge. It was completed in 1914 to connect two sections of Hertford College.
The bridge, and much of its current architecture, was designed by Sir Thomas Jackson. It was completed in 1914, despite its construction being opposed by New College.
