e-mosty March 2019 Long Span and Multiple Span Bridges - Page 8

INTRODUCTION LOCATION OF THE BRIDGE Turkey serves as an important crossing between Asia and Europe. Its rapid economic growth together with increased number of tourists, agriculture and transit transport has led to chronic traffic congestion. The 1915 Çanakkale Bridge (in Turkish 1915 Çanakkale Köprüsü) is located 200km southwest of Istanbul, spanning the Dardanelles Strait, which connects Lapseki District to the Gelibolu District (Gallipoli). The existing transportation network cannot accommodate all demands arising from the traffic growth. The strait forms a natural division between Europe and Asia and it connects the Marmara Sea with the Aegean and Mediterranean seas, as can be seen in Figures 2 and 3. To address these problems, the Turkish Government announced the Vision 2023 programme, which aims to increase the road, rail and sea transport capacities. Part of the programme is a new suspension bridge across the Dardanelles which is expected to improve the transportation network on the west side of the country, promote socio-economic growth and tourism. In particular it will provide an alternative route for European traffic to and from Izmir, Turkey’s 3 rd largest city, avoiding Istanbul. The bridge with its main span of 2,023m is going to be the longest span suspension bridge in the world when it opens to traffic. The bridge forms central part of the 321km long Kınalı -Balıkesir Highway, which will connect the O-3 and O-6 highways in East Thrace to the O-5 highway in Anatolia. The 1915 Çanakkale Bridge is part of the programme, which expands earlier major transportation projects such as the Gebze- Orhangazi-Izmir Highway with the Osmangazi Bridge. The project is expected to increase capacity, improve traffic flow and ease the present and future congestion problems. Figure 2: Location of the bridge on the map Source: Google Maps 1/2019
