Bridges

Bridges are an integral part of the road network, essential structures that link areas divided by rivers and rail lines. However, it is also conceivable that
once damaged by a natural disaster, a bridge could aff ect the road, river, or rail line over which it crosses as a result of a secondary disaster. Therefore,
bridge safety is of the utmost importance.

In addition to rebuilding old bridges to improve seismic resistance and weight bearing capacity, improvements include building new bridges when making road alignment and other improvements, and rebuilding bridges to eliminate traffic bottlenecks, creating wider roads. Through these improvements, the Bureau aims to ensure the safety of evacuation and transport routes for when a disaster strikes and strengthen the road network.

Major bridge projects currently underway include the Sekido Bridge (Fuchu City-Tama City) which crosses the Tama River, Matsue Bridge (Hachioji City) which crosses the Asakawa River, and the Wakashio Bridge (Shinagawa-ku) which crosses the Keihin Canal.
