上海是我国工业开放城市之一。随着国民经济的发展,开发浦东,提供有效的交通设施就显得十分迫切。国家计委于1980年11月批准了修建上海延安东路越江隧道的计划任务书。近年已列为七五期间上海十大重点工程之一。隧道主体工程正在紧张开挖中。本隧道规模较大,全长为二千二百六十米。浦西出口在延安东路的山东路和福建路之间,浦东出口在杨家宅路至烂泥渡路之间(图1)。隧道为单管双车道,供汽车和无轨电车对向行驶。隧道横断面(图2),车道宽7.5米,有效净高4.5米和车辆限速为每小时40公里。
Shanghai is one of the industrial open cities in China. With the development of national economy, it is urgent to develop Pudong and provide effective transportation facilities. The State Development Planning Commission approved in November 1980 the planning task book for the construction of the Yangtze River Tunnel at Yan’an East Road in Shanghai. In recent years, it has been listed as one of the top ten key projects in Shanghai during the Seventh Five-year Plan period. The main tunnel project is under intense excavation. The tunnel is large in size with a total length of 2,260 meters. Puxi is exported between Shandong Road and Yanjian Road in Yan’an East Road and Pudong in Yangjiazhai Road to Hundedu Road (Figure 1).
