Dilovası State Hospital Viaduct and Access Road

Featuring the tallest urban viaduct piers in Türkiye (46 m), this Kocaeli Metropolitan Municipality project crosses a valley to connect Dilovası State Hospital to the city's main arterial road. A 210 m, six-span viaduct and 1,100 m of connection road were built. The work involved 63,000 m³ of excavation and about 6,000 m³ of stone walls, using 8,000 m³ of concrete and 1,460 t of reinforcement steel. Completed together with pavements, stormwater lines, pedestrian and vehicle guard rails, anti-vandalism works and asphalt surfacing, the project ran from January 2023 to September 2024.
