YHT divided the road in two: Kocaeli Metropolitan Municipality built a tunnel under the railway to cross the High Speed Train route in Darıca. As a result of the work done due to the railway separating the School Street and Topçular Street, two streets were connected to each other by tunnel. Vehicles will now be able to transport the railway through the tunnel through the bottom.
The walls of the tunnel, which were reinforced with bored piles, were dug up and excavated. Previously, during the construction of the railroad, there was room for the underpass in the street section. This area was reached by excavation and a tunnel was created under the railway. 230 meter width of the project in the tunnel width was realized as 7 meters. The road width is 4 meter and the project is one and a half meter wide.
