The comprehensive project of Gong He Xin road consists of two parts——the elevated road project of Gong He Xin road and the project of north extension of No. 1 subway. The elevated highway project of Gong He Xin road is the backbone road of the city in north and south direction, started south from the first turning point of North & South elevated highway in junction with the north approach of the fly-over bridge of the internal circular boundary and ended north to the south junction of fly-over bridge of the Yunchuan road in north section of Puxi part of the external circular boundary, with a full length of approximately 9.65 kilometers, where the elevated part starts south from south side of the junction of Liuying road (connected with Gong He Xin road of internal circular boundary) and ends north to the north side of the junction of west Changjiang road, with a full length of approximately 8 kilometers. The scheme of constructing six elevated driveways plus ground six fast and two slow driveways for standard highway section and four elevated driveways plus ground six fast and two slow driveways for part of highway sections is adopted in this project. The ground roadway under the elevation is four-breadth road separated for motor vehicle and non motor vehicle, where the central vehicle roadway is two-way four-driveway, and the mixed auxiliary driveway (public traffic dedicated driveway and non motor vehicle driveway) are constructed in both sides.
Four-breadth roadway separated for motor vehicle and non motor vehicle is constructed for the road section from Changjiang xi road to the external circular boundary, where the motor vehicle driveway is two-way eight-driveway. The north extension section project of No. 1 subway has a total length of 16.8 kilometers, started from north end of the shanghai railway station, along with Datong road, Gong He Xin road, Yunchuan road to Fujin road in Yuepu area, Baoshan district, where the underground line is 2.18 kilometers and the elevated line is 14.62 kilometers. There are 12 stops in total, including 3 underground stops and 9 elevated stops. In the mean time, it is planned to set up a parking lot respectively near the Xinzhuang stop and Fujin stop. The first phase of north extension project has a total length of approximate 12.49 kilometers from shanghai railway station stop to Taihe road stop, including underground line of 2.18 kilometers and elevated line of 10.31 kilometers. There are 9 stops set up in total, only one of them is underground stop, others are elevated stops. Also a small parking lot is planned to be established in Xinzhuang. The comprehensive project is expected to have total investment of approximate RMB 4.62 billion, initiated at the end of Dec. 1999, and planned to be basically completed before the end of 2002.
