About how much did the Osmangazi Bridge itself cost to build, excluding the wider Istanbul-Izmir motorway?
The Osmangazi Bridge is a 2,682-metre suspension bridge across the Gulf of Izmit on the Istanbul-Izmir motorway. The bridge was inaugurated on 30 June 2016 and opened for traffic at the start of July. Anadolu Agency reported a construction cost of USD 1.3 billion for the bridge itself; its separately reported USD 6.3 billion amount covers the much wider motorway project. The USD 1.3 billion is a contemporary rounded report, not an independently audited final invoice.
