Ropsten metro station is the end station on line 13 on the red line of the Stockholm metro, located in the district of Ropsten. The station was opened on 2 September 1967 as the northeastern terminus of the extension from Östermalmstorg. The station was sited about 10–15 meters above street level as a preparation for an extension to Lidingö on a new bridge. There are now no plans for such an extension and the lines end in mid-air. The Ropsten station also includes the end stop on the Lidingöbanan tramway, a few meters about the street.
