群馬大橋

Gunma Bridge spans the Tone River with two directions of traffic and pedestrian paths running along both sides. The structure measures 280 meters and handles five lanes of vehicles moving in each direction.

The first direction of traffic opened in 1953, with the second direction not completed until 1997. This long interval reflects how the region's transportation system evolved gradually over decades.

The bridge carries a name chosen through public voting by local residents of Gunma Prefecture. This naming reflects how the community embraced the structure as their own.

The bridge functions as a main traffic route linking important facilities like the prefectural office and hospitals on either side. Pedestrians can use the dedicated walking paths to cross safely.

After dark the bridge glows with lights until 10 PM, casting reflections across the Tone River. This nighttime view can be seen from specific lookout spots in nearby neighborhoods.
