From cornice if you are coming from airport side, take left at the Oryx roundabout and take the khalifa street. Go straight on TV roundabout, Murkhya roundabout and after reaching passport roundabout, turn left. Don't take the expressway, but keep driving at the service road along the expressway towards Al Rayyan road. The service road is newly constructed. In 500 m, you will see the gate of US Ambassy on your right.
