Answer 1

They do it in the middle of the night. They go out with one of those big trucks that has the flashing arrow on top to tell drivers to change lines. They slowly drive along while someone in the back of the truck places barrels and cones on the road. By the time morning rush hour hits, the closure is already in place and the workers have a safe work zone.
