Project Description:

The Tomei Tamagawa Bridge renewal project was the first deck replacement project on the 6 lanes section with highest traffic volume in the Tokyo metropolitan area. Although the bridge had 100,000 vehicles per day, the deck replacement work was done while maintaining 6 lane availability with various new technologies. The economic benefits brought about by new method are immeasurable. This project will be the pioneer of deck replacement on heavy traffic routes.
