    The starting point of the route is connected to the Cheonan-si national road bypass route (Eopseong-dong three-way intersection), and the Jiksan intersection three-dimensional project (underpass) in the task section is under construction ('15.10-'19.10), passing through the water-repellent intersection that intersects National Road No. 34 It is a project to expand the habitually congested section of National Road No. 1 to 6 lanes as a route connected to the terminal Cheonan-daero (4 lanes round trip, intercity). Nearby are Hanwha Dream Green Apartment (under construction), Seohee Star Hills (under construction), Jiksan Station on Subway Line 1, gas stations, hospitals, and business facilities. Since the collision with private land is excessive and the relocation of existing road facilities (underground facilities, etc.) is unavoidable, the existing road is widened to one side (left) within the scope of application of the urban planning width of Cheonan City to minimize major obstacles and conflict with private land, and minimize the existing road A plan was made to minimize the use of facilities and the occurrence of abandoned road sites. In addition, considering the construction period of Jiksan Intersection Jiksan Underpass under construction, early detailed design was carried out for overlapping sections to ensure that there are no problems with the opening of the underground roadway.
