I'd note that the entire Santa Clara county expressway system all seems to be tagged as highway=trunk, and if memory serves, most of those roads (e.g., Foothill Expressway, Oregon Expressway, Lawrence Expressway) have significant numbers of intersecting traffic lights. I think that section of Central Expressway that's grade-separated (is it all but the northwestern end?) is actually unusual for the system. But it looks like the entire system is tagged as highway=trunk. Such a change would also disguise that there's a massive change in the character of the road (loss of divider, change in speed limit, and drastic change in lane widths) where it crosses San Antonio and turns into Alma Street. (If anything, the spot in the area where I'd question a highway=trunk tagging is Page Mill Road from El Camino to 280.) -David -- 𝄞 L.
