Straßenquerung could work. Querstraße also exists but it is used to describe a smaller street in relation to a main street like an intersecting street not the intersection. Word order matters with these smushes in German. But yeah, probably something with "quer" as root, that seems to be an old word. Now saying just "Querung" on its own seem a bit out of style, usually for crossing something, you now say "Durchquerung" or "Überquerung" or "Unterquerung" depending on the context, but it does exist on its own.
