I regularly get serious complaints from my constituents and local ward councillors about the state of bridges and underpasses. The complaints relate to the poor upkeep (both in terms of decorative state as well structural conditions / water seepage etc) due to years of neglect by TfL and other operators. These raise very valid concerns about safety, environmental impact and visual appearance of the area. Additionally some of these underpasses/bridges provide access to areas people use for their regular walks. What are TfL's policies for regular (cyclical) repairs and maintenance and how much is TfL able to influence other operators to maintain their structures too? Also, is there a list of ownership of such bridges/underpasses to help identify who is responsible for the unkeep?
