Oxbergsbron, Combined road and railway bridge in Älvdalen Municipality, Sweden

Oxbergsbron is a 101-metre bridge (27+47+27 m) over the Österdalälven at Oxberg, carrying both road and railway on a single shared carriageway. The railway track runs inside the road lane, so barriers close the road when a train passes; the bridge is too narrow for cars to meet.

Oxbergsbron was built together with the Älvdalen–Mora railway, which opened to traffic in 1900. On 2 November 2016 the Swedish Transport Administration closed the bridge to all traffic after an inspection found serious damage. The last span was lifted ashore shortly before midnight on 20 April 2017 and replaced by a temporary bridge. Construction of separate road and rail bridges is planned to start in 2025, with a two-year build time.

The road over the bridge is Vasaloppsvägen, the route between Mora and Sälen; the railway line it carries, Älvdalen–Mora, is used only by freight trains. The bridge stands at Oxberg, in Mora Municipality, though it crosses into Älvdalen Municipality.

The original bridge has been closed to all traffic since 2 November 2016, when Trafikverket inspectors found serious damage. A temporary replacement bridge carries traffic in the meantime. Construction of separate road and rail bridges is planned to start in 2025, with a two-year build time.

The bridge has an unusual design feature: the railway tracks are embedded directly into the road surface. This means vehicles must stop and the road is blocked with barriers whenever a train approaches.
