The vehicles are driving on the right side of the road. There is a large concrete elevated structure, likely a metro or highway overpass, which is common in major South American cities. The architecture and the general urban feel point towards Peru, specifically Lima. The bus on the right looks like a typical Lima public transport vehicle. I am fairly sure this is in Lima, Peru.

The elevated rail structure is clearly the Lima Metro Line 1. The surrounding urban landscape and the specific style of the bus confirm this is in the San Juan de Lurigancho district of Lima. The sky is overcast, which is very typical for Lima's "garúa" season. I am very confident this is in Lima, Peru.
