    Task section Gudori, Dongnam-gu, Cheonan-si, Chungcheongnam-do ~ Eupnae-ri, Jincheon-eup, Jincheon-gun, Chungcheongbuk-do, are included in the “2019 Balanced National Development Project” in January 2019.
    National Highway 21, which includes the business route, serves as an arterial road connecting the southwestern and northern regions of Jeollabuk-do, the northwestern region of Chungcheongnam-do (Asan, Cheonan) and the Chungcheong region (Jincheon-Eumseong). It is expected that traffic volume will increase in the Byeongcheon ~ Yongyong ~ Dongmyeon section when the factory is increased and connected to the 2nd Gyeongbu Expressway (Dongcheonan IC).
    Accordingly, only the Cheonan Byeongcheon-Jincheon section is in operation with two lanes, and the risk of traffic accidents is always implied due to poor alignment. Its purpose is to prevent power generation and traffic accidents.
