大渡橋

The Odabashi is a rigid-frame concrete bridge in Gunma Prefecture that spans across a wide waterway. The structure uses solid concrete supports and features gentle slopes in both directions to accommodate traffic flow.

The bridge was completed in 2004 and replaced an older drawbridge that had severe weight restrictions. The new structure transformed transportation between the two regions by removing barriers that had previously limited crossings.

The bridge connects two prefectures and is crossed daily by people moving between regions for work and travel. It has become a place where both locals and visitors can pause to take in the view and sense the scale of the waterway below.

The easiest way to reach the bridge is by train to a nearby station, from where you can walk or cycle to the viewing areas. The walkways are relatively level, making the visit comfortable for most people.

The bridge features different slopes on each approach, making the two sides asymmetrical in an interesting way that becomes apparent while crossing. This detail often goes unnoticed by visitors but reveals the engineers' specific design choices.
