Towers completed in world’s fourth longest suspension bridge between Istanbul and Izmir

Tower mounting in Izmit Bay Suspension Bridge, which has the world's longest fourth central span, has been completed. The towers stand 252 meters tall. The bridge is a part of a highway project that will decrease travel time between Istanbul and the Aegean city of Izmir from 9 hours to 3.5 hours.

The suspension bridge has been distinguished as the world's longest fourth suspension bridge with its 1,550 meter central span.
The bases of the suspension bridge tower caisson were laid in predetermined base points, along with anchorage basements and transverse beam manufacturing works.

The highway project is expected to be completed in 7 years. Currently 37 percent of the whole project is reported to have been completed.

A total of 5,520 personnel are working in the project and 1,316 pieces of construction equipment are involved. As the travel distance will be shorter compared to the current highway, decreasing travel time to 3-3.5 hours from 8-10 hours, it is foreseen that there will be a 650 million dollar savings made annually.

While it takes 1 hour and 20 minutes by car and 45-60 minutes by ferry, it is expected Gulf pass will take only 6 minutes.
