At NEXCO EAST Hokkaido Branch (Sapporo City Atsubetsu Ward), we will start replacing the bridge's floor version as an expressway renewal project.

　今回実施する工事は、E5A札樽自動車道　朝里ICから銭函IC間に位置する大野橋（おおのばし）の上り線（小樽方面）において、北海道の高速道路で初めて老朽化した鉄筋コンクリート床版を新しい床版に取り替える工事を行うため、終日対面通行規制を実施します。

We apologize for the inconvenience caused by face-to-face traffic during the period, but we ask that you make further efforts to drive safely when traveling in this section.

During construction Homepage for construction, Or traffic information etc. will be posted on the website such as DraPla so please refer to it when using the Expressway.

This work is necessary for safe and secure use of the Expressway, so please understand and cooperate with us.

1. 1. Construction section

札樽自動車道　朝里IC　⇔　銭函IC間（上下線）

2．通行規制期間及び規制内容

終日対面通行規制期間　平成29年9月5日（火）～平成29年10月15日（日）（41日間）

• Saturday, Sunday and public holidays are also regulated all day.
• The construction period may change depending on the weather and work progress.

3. Traffic restrictions

In the floor slab replacement work, we will reduce the section of each two lanes of up and down lines to one lane and consolidate it into Out-bound lanes and enforce face-to-face traffic control all day. During the several days at the beginning and end of the construction period, all-day overtaking lane restrictions will be imposed on the up and down lines as a preparatory step to switch to two-way traffic regulation.

Four. Construction overview

　札樽自動車道　朝里IC～銭函IC間に位置する大野橋は、昭和46年の開通から約46年が経過し、車両の大型化による輪荷重の増加で発生した微細なひび割れや、冬期間の凍結防止剤散布による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、床版の取り替え工事を実施する必要があります。

In order to replace the concrete floor slab part of the bridge, it is necessary to close the In-bound line (toward Otaru), but one of the 2 lanes of the Out-bound line (towards Sapporo) should be used for the In-bound line (toward Otaru). By carrying out transfer and face-to-face traffic, we will minimize the impact on traffic and carry out construction.

Main work contents

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.

Five. Request when using

1. The construction section spans approximately 3km and is reduced from the conventional two lanes on each side to one lane, and one-sided lanes on each side (two lanes up and down) are restricted.
   For this reason, the road shoulder is narrow in the one-lane section on one side, so when traveling, please comply with the regulation speed and secure the inter-vehicle distance to be careful of a rear-end collision accident.
   Also, as there is a large lane shift in order to shift to the one-lane section on one side, please follow the local information signs.
2. During the construction period, we will provide construction regulation information as well as call attention to construction regulation information that utilizes information boards, road signs, and simple information boards, and cautions to drive safely. Before riding, please check the above information before riding safely.
3. Please check the latest traffic restrictions and traffic jam information before going out.
