Cooper Street and Delaware Avenue are four-lane roads, with light
rail/tram tracks in the outer lanes. Obviously one could simply apply
railway=* to the highway, but that would not show the individual
tracks. So I drew the tracks in their individual positions, but at
high zooms it renders with the tracks completely outside the roadway.
It would not be correct to draw two roadways, one in each direction
(like on 4th Street to the east), since, unlike 4th Street, these are
single carriageways.

Is there any better way to do this? Also, is it proper to place
railway=level_crossing at every node where the centerlines of railways
and highways cross, even if the railway is simply entering or leaving
the highway right-of-way (like on 4th Street to the southeast)?
