More road construction scenes

This is one of the main roads in town. It is like this on both sides of the road, with two small lanes of traffic delicately balanced in the middle of the mess.

They are putting in pipes. I think it is related to the subway construction in some way. 

Above and below are scenes from the main east-west artery through town. Shops along the subway construction route have been hidden from view by metal barriers for almost four years, so most have gone out of business. When the barriers come down, I won't recognize the city. I have no idea what lurks behind those metal shields.

Again, this is the main artery through town. The part in the middle is under construction. But tomorrow, it may be the outer parts of the road that are under construction. From one day to the next I never know what the detours will be. It changes quite often.

You can't tell much in this photo, but it is a big gaping hole in the street. I presume it will be a subway entrance area, as it is several stories deep.
