Fixed crossing in the context of "Ferry"

The Dardanelles (/ˌdɑːrdəˈnɛlz/ DAR-də-NELZ; Turkish: Çanakkale Boğazı, lit. 'Strait of Çanakkale'; Greek: Δαρδανέλλια, romanized: Dardanéllia), also known as the Strait of Gallipoli (after the Gallipoli peninsula) and in classical antiquity as the Hellespont (/ˈhɛlɪspɒnt/ HEL-isp-ont; Classical Greek: Ἑλλήσποντος, romanized: Hellḗspontos, lit. 'Sea of Helle'), is a narrow, natural strait and internationally significant waterway in northwestern Turkey that forms part of the continental boundary between Asia and Europe and separates Asian Turkey from European Turkey. Together with the Bosporus, the Dardanelles forms the Turkish Straits.

One of the world's narrowest straits used for international navigation, the Dardanelles connects the Sea of Marmara with the Aegean and Mediterranean seas while also allowing passage to the Black Sea by extension via the Bosporus. The Dardanelles is 61 kilometres (38 mi) long and 1.2 to 6 kilometres (0.75 to 3.73 mi) wide. It has an average depth of 55 metres (180 ft) with a maximum depth of 103 metres (338 ft) at its narrowest point abreast the city of Çanakkale. The first fixed crossing across the Dardanelles opened in 2022 with the completion of the 1915 Çanakkale Bridge.

A bridge–tunnel is a persistent, unbroken road or rail connection across water that uses a combination of bridges and tunnels, and sometimes causeways, and does not involve intermittent connections such as drawbridges or ferries.

Bridge–tunnels are a form of fixed link or fixed crossing which replaces ferry service. Fixed links are often, but not necessarily, intercontinental links between continents or transoceanic links to offshore islands.
