It turns out that there are some projects planned for South East London. It remains unclear why these don't make it into the map or list of road projects to 2022, I suspect because they are relatively minor projects by comparison.
But the list does include:
A205 Devonshire Road junction with London Road outside Forest Hill Station – Junction layout improvements to allow for better pedestrian crossing facilities. These works are likely to be carried out in Spring 2018.
A205 Catford Road junction with Thomas Lane & Canadian Ave – New road layout to include improved pedestrian crossing facilities and reduced vehicle queuing with the aim to improve bus journey time and reliability - These works are likely to be carried out in early 2016.
Other projects can be found in the comment sections at http://talklondon.london.gov.uk/travel/m...h#comments
So we finally have a date when the main junction in Forest Hill will be improved for pedestrians, and it is only 3 years away!
