discovered another error while browsing the map near monumento and malabon zoo. this time it's in Caloocan, Malabon, Valenzuela. the segment of MacArthur is a dual carriageway i.e. it should have a center island. no idea of the other end since I'm only familiar with it from Mento up to marulas...in bulacan it's already a two-way, single carriageway road...

expect routing errors in the area as not all streets have crossings
