Hello, I downgraded this section of Route 50 to trunk for reasons whammo suggested. It has tight ramps, a relatively low speed limit, low/narrow medians, sidewalks separated by a curb and grass, and level crossings on the ramps adjacent to the main carriageways. While it is common for some freeways to have one or two of these characteristics, all of them in one road can indicate that it is more of an arterial road that is controlled by ramps (rather than a freeway), which is a good candidate for highway=trunk/primary/etc. and expressway=yes tagging.
