To resolve the long-time traffic congestion and safety problems in Gangshan District and address the traffic diversion of County Highway 186 after the completion of the Ciaotou Science Park, TBKC performed the feasibility survey according to the “Regulations for Expressway Construction and Interchange Improvement” and submitted the report to the Freeway Bureau for evaluation. On January 31, 2020, the Freeway Bureau granted a conditional approval of the report at the “Interchange Construction and Improvement Review Board Meeting.” On August 30, 2020, KHCG submitted the feasibility survey report to MOTC to forward to the Executive Yuan, which approved the project on May 7, 2021. The Freeway Bureau will proceed with the integrated planning, environmental impact comparative analysis (EICA), design, and construction, while KHCG will take charge of the undertakings including land expropriation and road expansion. If everything goes smoothly, the interchange will start service in 2026.
