It must be the camera angle and lack of perspective, you could easily drive a car (and the backhoes being used to create it) down it. It is quite wide
I didnt measure it, but it is about 12 to 15 feet across, which is about 2 to 3 times the average width of sidewalks in North America.
In the picture, my car was parked in the space off the road and there was room on either side of the vehicle. The sidewalk is wider than that is...
