Construction details

By replacing the deteriorated existing concrete deck ^* with a new deck, Expressway will be reborn as a safe and comfortable one.

A deck is a structural member that directly supports automobiles passing through bridges and transmits the load to the girder.

Precautions when using

Traffic congestion is expected, so please allow yourself plenty of time when traveling.

Requests when passing special vehicles
Due to this traffic regulation, Special vehicles exceeding 3.0m in width cannot pass.
Customers using the service, please take a detour to the surrounding roads.
Also, please note that if you have obtained a special vehicle traffic permit (*) only for Expressway routes, you will also need to obtain a permit for general roads.
