If you use this section, please make further efforts to drive safely and make sure you have enough time to go when you use it.

In addition, we are working to shorten the construction period, such as using precast products produced in the factory in advance, When the construction period is postponed (use a spare day) due to bad weather, etc. Tohoku Expressway Between Ichinoseki IC and Wakayanagi Kinari IC (In-bound), the maximum distance is 1km between 15:00 and 18:00 on November 25 (approx. 5 minutes), and between Tsukidate IC and Wakayanagi Kanari IC (Out-bound), November 23. A maximum of about 2km between 9:00 and 15:00 (passage time +10 minutes) and about 1km at 16:00 on the 25th (passage time +5 minutes) Is predicting congestion. Customers who are planning to use ICs near the regulated section on November 23 and 25, who are predicting the occurrence of traffic congestion, ask for the cooperation of the detour, such as avoiding the traffic congestion prediction section. I will do it. On other days, we do not predict the occurrence of traffic congestion.

Four. Construction content

　東北自動車道　築館IC～若柳金成IC間に位置する三迫川橋は、開通から約40年が経過し、車両の大型化による輪荷重の繰り返しで微細なひび割れ、冬期間の凍結防止剤散布の塩分などが原因となり、コンクリート床版の劣化や鉄筋に錆が生じているため、抜本的な老朽化対策工事を実施する必要があります。

By replacing the deteriorated existing concrete slab with a new slab, it will be reborn as an Expressway that can be used safely and comfortably.

Construction overview

• A floor slab is a structural member that directly supports an automobile or the like passing through a bridge and transmits the load to the girder.

Also, Because a spare day may be used due to bad weather etc. , For customers who are planning to use the construction section on November 23 and 25, when traffic congestion is predicted, we would appreciate your cooperation in changing the IC used.
• [2] Since the driving lane and shoulder are narrow in the face-to-face traffic restricted section, observe the regulated speed when traveling, secure the distance between the vehicles, and pay sufficient attention to rear-end collisions. In addition, the lane changes greatly before and after the face-to-face traffic restricted section, so please follow the local information signs and so on.
