Shin-Imai Bridge, Road bridge in Edogawa, Tokyo, Japan.

Shin-Imai Bridge crosses the Shin-Naka River, connecting residential areas of Edogawa through a steel and concrete structure. It provides a key passage for both vehicle and pedestrian traffic between the river's two banks.

The bridge carries Tokyo Metropolitan Route 50 (Shin-Ohashi-dori) over the Shin-Naka River, extending the planned radial road 31 toward Chiba Prefecture. The project was approved on 6 March 1984 and the bridge opened on 23 November 1997. Its opening eased congestion on the neighbouring Imai and Mizue bridges.

The bridge carries Tokyo Metropolitan Route 50, the Shin-Ohashi-dori, and its opening on 23 November 1997 relieved congestion on the older Imai Bridge and Mizue Bridge, strengthening access to Chiba Prefecture. Its name pairs it with the neighbouring Imai Bridge over the old Edogawa. The steel girders were fabricated and erected by Matsuo Kyoryo.

The bridge welcomes both pedestrians and vehicles with multiple access points on each side. It links major roads that make navigation through the area straightforward.

The bridge's steel superstructure, weighing 540 tonnes, was fabricated and erected by Matsuo Kyoryo Co.; the 121.5 m main span is part of a 675.9 m elevated section that carries the road over the Imai and Shinozaki highways.
