History

Construction on Dongjakdaegyo commenced on October 18, 1978, and Seoul Mayor Jachoon Gu, Deputy Prime Minister Deokwoo Nam, and Minister of Construction Hyeongshik Shin participated in the groundbreaking ceremony. At the time of commencing construction, Dongjakdaegyo was the first bridge in Korea to have the langer-arch design, and was scheduled to open in September 1981. The reason for using the langer-arch design for this bridge was because a steel plate was used instead of a concrete plate for reducing the bridge weight by designing to allow the Seoul Line No. 4 to pass. At the time, the construction of Dongjakdaegyo was carried out as construction of a civil investment method by the investment and construction delegated to Daewoo Development, similar to Wonhyo Daegyo, therefore there was a plan to receive toll fares for a period of 20 years. At the time of construction, Dongjakdaegyo was the widest bridge in Korea.
