After the road construction, there are times when the next is in the next state, but why not pave properly?

The condition of the next step as shown in the photo is temporary pavement (temporary restoration) performed on the excavated road, and since all construction has not been completed, the final pavement (main restoration) cannot be performed.
Temporary pavement (temporary restoration) is performed in a variety of cases.
In Yokohama-shi, about construction (new construction, repair) in public utilities such as water supply, sewer, gas buried in road, we coordinate with company to plan prevention of unnecessary digging and shorten construction period. At this time, temporary pavement (temporary restoration) will be performed so that the next company can be constructed immediately after the construction of one company is completed.
Even in the case of construction by a single company, for example, in the case of night construction that requires several days, temporary pavement (temporary restoration) will be performed after the daily construction is completed to secure daytime traffic.
In this way, temporary pavement (temporary restoration) is performed in various cases, and the final pavement (main restoration) is performed after all construction is completed.
In addition, at the time of temporary pavement, the mark of each company is painted on the road surface as follows so that it can be seen that it is temporary restoration.
