I generally consider the minimum requirements for motorway as dual carriageway, with each carriageway having a minimum of two lanes, barring temporary traffic controls (such as a reduction to one lane each way, undivided, very common when a DOT needs to restrict access completely to one motorway for routine maintenance or immediately after a major disaster; most frequently personally experienced in California, Oklahoma and Kansas, and routinely planned for to the extent that permanent crossover "X" links are installed regularly in Kansas and Oklahoma).
