Marieholmsbron, Railway bridge in Gothenburg, Sweden.

Marieholmsbron is a 907-metre railway, pedestrian and cycle bridge in Gothenburg, running from Gamlestaden over the Säveån river, the Marieholm area and the Göta älv to Tingstad on Hisingen. Its Göta älv span is a swing bridge with a clearance of 5.9 metres, opened remotely from the Göta älv bridge control tower. The bridge carries the Bohusbanan line and links the port railway to the national network.

The first Marieholmsbron opened in March 1909, a metal swing bridge that was then Sweden's longest railway bridge; it was built as a bridge rather than an embankment because the firm ground lay deep below Marieholm. It was replaced in 1996 by a concrete bridge a few metres upstream, again with a swing span over the Göta älv. A second, Södra Marieholmsbron, opened on 29 March 2016 to add capacity and reduce vulnerability.

The bridge serves as a daily passage for commuters moving between different parts of the city and has become a familiar landmark in the urban landscape. Passing trains shape the pace and rhythm of this area.

The best way to experience the bridge is by train, which travels slowly across the structure and offers views from the carriage windows. A separate pathway for pedestrians and cyclists runs alongside the tracks and can be accessed from several points along the route.

The 1996 bridge is remotely operated from the control tower of the Göta älvbron, and its low clearance of 5.9 metres means it must open for most vessels. The southern span over the Göta älv carries a foot and cycle path on its south side.
