Yesterday the UK government published a consultation on options for a new Thames Crossing close to where I live. The web page is here: https://www.gov.uk/government/consultations/options-for-a-new-lower-thames-crossing
Of course, I made straight for the map of the possible routes - all very broad-brush at the moment. What surprised me most was that, despite owning its own mapping agency the Ordnance Survey, the government has used an OSM Mapnik rendering for its base map! Maybe this is a regular occurrence, but it's a first for me.
