I don't know what the area's called (can't seem to find any mango trees at least from this angle!), but it's the next bridge upstream after Tullahan Bridge in Malabon. It's not located in any road map because this makeshift bridge along R. Delfin St. was temporarily made for light to moderate vehicles rerouted from McArthur highway as the Tullahan Bridge is being renovated. I hope that helps? :-)
