Fatih Sultan Mehmet Bridge
bridge in İstanbul, Turkey
The Fatih Sultan Mehmet Bridge ("Sultan Mehmed the Conqueror Bridge"; Turkish: Fatih Sultan Mehmet Köprüsü, abbreviated as F.S.M. Köprüsü), also known as the Second Bosphorus Bridge (İkinci Köprü), is a bridge in Istanbul, Turkey spanning the Bosphorus Strait (Turkish: Boğaziçi). When completed in 1988, it was the 5th-longest suspension bridge span in the world.
The bridge is named after the 15th-century Ottoman Sultan Mehmed the Conqueror, who conquered the Byzantine capital, Constantinople (Istanbul), in 1453. It carries the European route E80, Asian Highway 1, Asian Highway 5 and Otoyol 2 highways.
Three other bridges that connect Europe and Asia are located in Turkey, which are named Yavuz Sultan Selim Bridge, 15 July Martyrs Bridge (formerly known as Bosphorus Bridge) and the 1915 Çanakkale Bridge.
Location
The bridge is situated between Istanbul Hisarüstü (European side) and Kavacık (Asian side). It is a gravity-anchored suspension bridge with steel pylons and vertical hangers. The aerodynamic deck hangs on double vertical steel cables. It is 1,510 m long with a deck width of 39 m. The distance between the towers (main span) is 1,090 m and their height over the road level is 105 m.

Why this record matters
The phrase “bridge in İstanbul, Turkey” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated May 7, 2026. The linked authority identifier is Q369967. Authority coordinates are 41.091, 29.061. 1 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1988, 1453 and 1915.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
