Watling Street is a historic route in England that crosses the River Thames at London and which was used in Classical Antiquity, Late Antiquity, and throughout the Middle Ages. It was used by the ancient Britons and paved as one of the main Roman roads in Britannia. The route linked Dover and London in the southeast, and continued northwest via St Albans to Wroxeter. The line of the road was later the southwestern border of the Danelaw with Wessex and Mercia, and Watling Street was numbered as one of the major highways of medieval England.

The name "London Bridge" refers to several historic crossings that have spanned the River Thames between the City of London and Southwark, in central London since Roman times. The current crossing, which opened to traffic in 1973, is a box girder bridge built from concrete and steel. It replaced a 19th-century stone-arched bridge, which in turn superseded a 600-year-old stone-built medieval structure. In addition to the roadway, for much of its history, the broad medieval bridge supported an extensive built up area of homes and businesses part of the City's Bridge ward and its southern end in Southwark was guarded by a large stone City gateway. The medieval bridge was preceded by a succession of timber bridges, the first of which was built by the Roman founders of London (Londinium) around 50 AD.
