I’ve driven through the District of Columbia retracing current and “old” routes (old is played for laughs) and with DDOT’s reputation for not signing the routes notwithstanding, One has to rely on the goog or OSM (which, btw, conflict with each other). US 29 is well signed as DC had recently put up new signage for it, while 50 and to a greater extent 1 seriously lack signage especially around the national mall. 1A is not signed at all in DC (but signed beautifully in Maryland) I may put in a pull for US-29 to add shaping points based on the accurate field check but I hesitate at this time without logs to adjust 1 or 50 (neither of which have a zig-zag). This pull will go in no earlier than 9/1 as I’m on the road still. There is no assigned maintainer for DC.
