The straight-line distance from Song Jian's current location to Fifth Avenue was three kilometers, but to actually get there, he'd need to travel more than five kilometers along the streets, passing numerous hospitals, schools, and supermarkets along the way.
Fifth Avenue was a pedestrian street, surrounded by three high-end residential communities. Apart from three high-rise buildings, all the other houses were rowed villas or detached houses. The task hints didn't specify the exact location of Dr. Ebsiting. Even if Song Jian made it to Fifth Avenue, finding the doctor would likely be quite a challenge.
The Urban Waste Collection Center, or 'garbage station' as most people called it, was situated on the western side of the city's ring-road highway, ten kilometers from Song Jian's location at Camel Square.
