Centralbron (Swedish: [sɛnˈtrɑ̂ːlˌbruːn], "The Central Bridge") is a major bridge in central Stockholm, Sweden, connecting the northern district Norrmalm to the southern Södermalm. It is 1,200 metres long and consists of two viaducts passing over Söderström ("Southern Stream") and Riddarfjärden close to Norrström ("Northern Stream") with an interjacent elevated section traversing and the adjacent eastern waterfront of Riddarholmen. Centralbron has a capacity for 130,000 cars per day. It is paralleled by the bridges (Södra and Norra järnvägsbron) and the tunnel of a two-track railway used by the commuter and freight trains. Centralbron does partly go on top of the Metro which opened on this stretch 1957 and planned together with the bridge.
