Description

Janson's Bridge is a canal bridge built around 1816, likely designed by engineer John Fletcher based on the original plans of John Rennie, whose route for the canal was approved in 1792. The bridge is constructed of squared, coursed limestone and features a limestone string, copings, and a rounded fender course. It has an elliptical arch supported by rusticated voussoirs and a keystone. The ramped parapets have flat tops and end in pilasters. The bridge is approximately 3.5 meters wide between the parapets.
