The Bridge of Shutoko No.1 across the Tama River Being Renewed
The expressways built in the mid-20th century requires renewal soon. In 2022, construction was underway to renew bridges on three expressways that cross the Tama River: Tomei Expressway, Chuo Expressway, and Shutoko (Metropolitan Expressway) No.1. This photo shows the renewal work on the Tama River Bridge of Shutoko No.1.
This photo shows the renewing work of Shutoko No.1. New bridge beams were being built next to the old bridge. The cable-stayed bridge, Daishi-bashi, is not the target of the renewing work. In this photo, Shutoko bridge is hidden behind the new bridge beam.
After the new bridge beams completed, they were moved sideways to replace the old one. This approach was adopted because there was no space to build a temporary bridge for detouring. The switch was carried out in 2023 May, with traffic being closed for two weeks.
