is this really a seperate carriageway? from all sources i looked at it's just a bus bay

Shouldn't light rail level crossings be tagged as railway crossings instead of tram crossings?

this section of Powell (13th Pl - 12th Ave, maybe up to Milwaukie) should be mapped as two-way highways to account for the central turn lane

Regarding expressway=yes for Milwaukie Expressway: according to OSM wiki, undivided highway without full access control shouldn't be tagged as expressway=yes. What do we think?

mysterious unconnected way here. the new garage could use updates but it is difficult even with updated imagery

intersection has been reconfigured - see USGS imagery (comfirmed with google streetview for reference)

how do you tag instances like this where the traffic direction is opposite from the normal traffic direction of this jurisdiction? (LHT here)

there is no yield signs (or any signage) for east-west traffic, and no roundabout or oneway signages anywhere either. does this still fit the mini-roundabout tag requirements?

pond to be mapped
