I had the same feeling when visiting New-York. Their highways have overpasses. What you saw in Beijing is probably not highways, it is just the normal 8-lanes roads that squares the city. Traffic is a mess in the city, for sure. I heard they sell 1000 new cars everyday in Beijing, so it is not an easy task to dissolve the jam. They have a law forbidding every car one day per week, based on your plate number, so wealthy people buy two, and less wealthy use public transport or bike once a week at least.
