For the construction of the Black Sea Coastal Highway, the project costs approximately 4,2 billion dollars.
million cubic meters of deposit/fill, 180 million tons of fortification and 3 million cubic meters of concrete were used/produced.
By means of excavation, the total length of the highway was reduced by 17 kilometres from 559 down to 542 kilometres.
kilometres of the excavations were realized in the Bolaman-Persembe road and 2 kilometres in the Samsun freeway. The project includes 263 bridges totalling 27 kilometres, 12 single tube tunnels totalling 41 kilometres and 20 double tube tunnels totalling 18.5 kilometres.
The first big part of the highway stretching from Samsun to Sarp Frontier put out to tender in 1987 was for the part between Carsibasi-Trabzon-Arakli, where traffic was heaviest.
Because the necessary allowance was not granted from the national budget for this and the following tenders, the project did not advance as planned. In order to meet the deadline and finish the highway, as of 1997 it was decided to put out the remaining parts to tender with foreign credits. Out of 16 sections, 12 were externally credited, 4 were covered by the national budget.
