Four. Traffic regulation contents

In carrying out the construction, we will implement face-to-face traffic restrictions (up to about 5.5km) throughout the day. Since heavy traffic is expected to occur on both the upper and lower lanes, we will operate in 3 lanes (2 + 1 lanes). In order to change the number of lanes that can be passed according to the busy hours, the road zipper system will switch lane operations in a short time during the hours when traffic is relatively light, both in the early morning and in the afternoon. By changing the direction of securing two lanes according to the time of day when customers are frequently used, we will operate lanes so as to reduce inconvenience to customers.
During the switching time, it may be crowded because it will be temporarily operated in one lane on each side. Please observe the regulated speed and follow the local information signs.

• Please see Attachment-1 [PDF: 882KB] for details on switching lanes using the road zipper system.

6. Outline of floor slab replacement work

Floor slab replacement work is a work to replace a concrete slab that is damaged due to deterioration or an increase in large vehicles with a new prestressed concrete slab that has higher durability. In addition, high-performance floor slab waterproofing is also implemented on the waterproof layer to prevent deterioration of the concrete floor slab.

Floor slab replacement work (Example of "Hokuriku Expressway Takase Bridge (In-bound line)" carried out in the fall of 2018)

Damage to Sakaehashi and Kaikugawabashi

◇ Efforts to minimize inconvenience to customers due to construction work

Adoption of precast products for the purpose of shortening the construction period and improving quality

• By adopting precast (products manufactured in advance at factories, etc.) PC floor slabs, the construction period is shortened and the regulation period is shortened as much as possible.
