The bridge is owned by the state and Banedanmark, the Danish railway authority, is responsible for its maintenance.

On the bridge there are two railway tracks, two narrow lanes for cars to cross as well as a sidewalk for pedestrians.

When the new Little Belt Bridge came into use in 1970, the old bridge lost its function as the main traffic line for cars between Funen and Jutland; however, it is still used as the only railway bridge between Jutland and Funen and thus the only railway line connecting Jutland with Zealand as well, as well as to carry traffic between Fredericia and Middelfart and their neighbouring villages.

[3] Rail traffic continued almost uninterupted, as the bridge is the only connection over Little Belt for trains.

In 2015, guided 'bridgewalking' tours on top of the framework were introduced at the Little Belt Bridge.
