I see that the same part many times, why?

In Yokohama City, about construction (new construction, repair, etc.) in public utilities such as water supply, sewerage, gas, etc. where roads are buried, we will coordinate with companies and continue multiple constructions. After the construction is completed, temporary pavement (temporary restoration) of the road is performed so that the construction of the next company can be performed immediately, and the final pavement (main restoration) is performed after all construction.
For this reason, construction at the same location will be performed multiple times in a short period of time. We believe that it is beneficial for road users because it can shorten the construction period.
