A series of 80 metal discs delineating a route on London’s Tower Bridge and connected by a blue line. On the discs are the names of people who worked in the construction and maintenance of the bridge. After each name, a disc appears with an illustration describing the role of that person.
The discs were placed on the bridge in 2016.

A view of part of the route can be seen in the following photo taken on the same day Click for a larger image
