The accident occurred Wednesday near the town of Gebze, in Kocaeli province, during the construction of the North Marmara Highway.
Kocaeli Gov. Huseyin Aksoy says rescuers are still trying to reach the two trapped workers, adding that they are believed dead.
Aksoy told reporters that "there are fears concerning their (showing any) signs of life."
News reports say the four workers plummeted from the top of the viaduct along with the concrete block.
This is the latest in a string of construction accidents in Turkey that have raised concerns about safety conditions for workers. (Compiled by Dong Feng)
