https://travelmapping.net/hb/showroute.php?r=mar.a101- N9 -> 1014 which refers to A101's exit at km4.
- I've traveled the route today. The first eastbound km post is km4, i.e. the beforementioned exit. It is the first exit which is not signed with white (urban) signs. If I didn't missed it, there is no motorway beginning sign. OSM does indicate 'A101' further to the next exit but I'd truncate A101 to exit 1014.
- The remainder is indicated on maps as Autoroute Urbaine de Casablanca. It's a grade-separated dual carriageway with 80km/h speed limit. There are bus stops etc. We might add the route as a 'selected freeway' route, or simply remove it from HB. I'm the only traveler so far.
