When jurisdiction of Taipei City changed to the central government in 1967, in order to allow the mass development of the city, the city government launched the first four-year public construction project and built the main thoroughfares to the suburbs. Zhongxiao E. Rd. was the main thoroughfare leading to the Eastern District. The construction of Zhongxiao E. Rd. Sections 3 and onward led to the rise of the Eastern District developments. These factors led to the Eastern District overtaking the Western District as the new business center of Taipei. The development of the Xinyi Planned District and the opening of the Wenshan Line and the Nangang Line rapidly boosted the development of the Eastern District.
