The vehicles are driving on the right side of the road, which is standard for North America. The concrete road surface and the style of the highway overpass suggest a major US city.

I suspect this is in Chicago, Illinois. I am moderately sure.

The concrete barrier and the specific style of the overpass are very characteristic of the Chicago expressway system, particularly the Kennedy or Dan Ryan Expressways. The lush green trees lining the embankment confirm a mid-summer setting in the Midwest. The traffic density and road markings are consistent with a major US metropolitan highway. I am fairly confident this is Chicago, Illinois.
