Dongda Highway (district boundary-G1503) is located in the south of Pudong New District, connecting Daye Highway in Fengxian District to the west and Lingang Avenue to the east. "Daye Highway - Dongda Highway - Lingang Avenue" is planned as the main highway / arterial road, which is an important east-west passage in the south of Shanghai. In order to strengthen the traffic connection between Pudong New District and Lingang New Area, to improve the road network structure in southern Shanghai and to alleviate the traffic pressure of S2, the overall scheme of reconstruction project of Dongda Highway (district boundary-G1503) is studied. The functional orientation, construction conditions, flow forecast analysis and main technical standards of the road are briefly introduced, and two overall schemes are compared. After the multi-aspect demonstration, the scheme of the main line reconstructed with node overpass bridges is recommended to realize the continuous traffic flow of the main line.
