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.

We anticipate traffic congestion, so please leave plenty of time.

Requests when passing special vehicles
Due to this traffic regulation, Special vehicles exceeding 3.0m in width cannot pass.
