2. Construction overview

Of the widening construction of the Hamano Viaduct, the live intersection is constructed while passing through the intersecting national highway No. 16 and the main local road Hamano, Yotsukaido, and Naganuma lines, so a special support work (*1) was installed at the top of the intersection due to night traffic closure. After that, we started to develop the special support work.

However, on the morning of October 6th and the morning of October 31st, the special support work on the Out-bound line side and the In-bound line side was lost due to the rear-end collision of the vehicles passing at the intersection, so the prefabricated model spider All have been removed, including. The vehicles passing through the intersection were all vehicles that violated the "height limit (3.8 m)" and "no large freight vehicles allowed".

There is a sidewalk under the special support construction, which is used as a school road for elementary and junior high school students and as a community road. If a similar method is used in the future, an accident due to a similar violating vehicle may cause third party damage.

Therefore, at the actual intersection, during the above period "Whole traffic closure" In addition to securing pedestrian traffic safety and construction safety, we decided to deploy construction while shortening the construction period.

*1: Special support work is a special structure that supports the formwork for pouring concrete.
