Background (1) The national road project III of Beiijng-Zhuhai national trunk road (including Junshan Yangtze Bridge) in Hubei province is part of the "Two longitudinal and two lateral" national trunk roads, which shall be built in the year of 2000 as planned by the State Council. The Wuhan Junshan Yangtze River Bridge is an extra-bridge located at the joint section of the Beijing-Zhuhai national trunk road and the Shanghai-Chengdu national trunk road. In December 1992, the Hubei Provincial Communications Administration commissioned the desk study on Hubei section of Beijing-Zhuhai national trunk road. Therefore, in November 1993, the Hubei Provincial Communications Planning and Design Institute (HPCPDI) completed the pre- feasibility study report of Hubei section of Beijing-Zhuhai national trunk road. In December 1993, the Hubei Provincial Planning Commission and the Hubei Provincial Communications Administration submitted the proposal of the project to the State Planning Commission. In September 1995, the additional report related to the two sections of Shanghai-Chengdu route. (2) Entrusted by the HPCPDI in March 1994, the Highway Research Institute of the Ministry of Communications (a First Class Certificate holder for environmental impact assessment issued by the National Enviromnental Protection Agency (hereinafter NEPA)) undertook the environmental assessment study for the national road project III. Entrusted by the HPCPDI in May 1994, the Shanghai Ship & Shipping Research Institute undertook the environmental impact assessment study for the Beijing-Zhuhai national trunk road Junshan Yangtze river bridge engineering project. The terms of references of the environmental assessment for the project mentioned above went through the examitiation by NEPA in July and October respectively. (3) The EIA report and the EAP (environmental action Plan) for the national road project III and the Junshan Yangtze Bridge were submitted to the World Bank expert in September 1996.

Engineering Brief The main road of the project is composed of two parts: Dawu-Shenshan road section of Jing-Zhu route (Beijing-Zhuhai national road) (including Junshan Yangtze bridge); and Wuhan East section and West section of Hu-Rong route (Shanghai- Chengdu national road). The auxiliary enginering work of road includes three connection roads: Dawu link, Huayuan link, and Xiaogan link. The main road is built by motorway standard with total length of 205.408 km; the three connection roads are built by class II standard with total length of 39.7 km. The Dawu-Shenshan section is 148.365 km long, with 12 interchanges, 55 separate grade crossings, 267 underpasses, 6 extra-large bridges, 5 large bridges, with total investment cost about CNY 529.76 million. Wuhan East section of Hu-Rong route from Shenshan to Baoxie is 44.526 km, with 4 interchanges, 43 separate grade crossing, 49 underpasses, with total investment cost about CNY 860 million. Wuhan West section of Hu-Rong route from Zhushan to Yongan is 12.517 km, with I interchange, 7 separate grade crossings, 26 underpasses, with total investment cost of about CNY 248 million. Dawu link from Dawu interchange to national road 107 is second class road, with total length of 9.1 km, with I large bridge of 286.4 m long, I medium bridge of 42.9 m long, with total investment cost about CNY 38.498 million.

Present Situation of the Environment 3.1 Landform and topographical features The area along this route is vast with great landform fluctuations. From Dwu to Xiaohe township of Xiaochang is heavy hilly area; from Fu river to Junshan is plain lake area; and the other areas are plain hilly. Soft soil is dispersed over this project area, so that there are about 22.7 km road section of this project have to be treated artificially. Meanwhile, the ground surface is characteristic of long time temporary water storage, with higher water table. The soil quality is poor with great water content; therefore, the soil shall have to be transported from a long distance for subgrade and pavement, which makes the engineering work difficult and the cost up. The geologic conditions of the area in the north of Fu river is quite good, according to the investigation, no areas with poor geologic conditions, such as landslide, rock slide, and soft ground, have been found. Ancient stratum has been found from Dawu to Huayuan, with bedrock along the route shallowly buried and the outcropping rock can be seen everywhere. The stratum from Huayuan to the north of Fu river is dominated by the middle and ancient time Pleistocene series with hard soil texture, along the route. The slope the irrigation canals and ditches is not only steep but also stable with high load capacity. The good geologic conditions provide reliable subgrade for the engineering work. The low-lying land in the road section from the south of Fu river to Junshan is characteristic of short term deposit, soaked with surface water and underground water for a long time, with soft soil texture and low load capacity, except for the highland of Dushan, Hengshan, Zhashan, Junshan, etc. within Caidian area, which has relatively good geologic conditions. The road section in the east of the West Lake area is mainly soil ground with thick and deep soft soil layer. The sections from Zhushan to Yangan and from Jinkou to Baoxie belong to corrosion hilly area. Due to the corrosion by surface runoff, the landscape with topographical features of hills zigzagged with ditches has been formed. The average subgrade filling height shall be 3.5 - 4 meters. The section along the route is dominated by soil ground with relatively good geologic conditions with a few rocks; and poor geologic conditions having not been discovered. 3.2 Meteorology and hydrology The impact areas of this project are located in the middle and low latitude, belonging to tropical continental monsoon humid climate featured with clear four seasons, long frost-free period. The annual average temperature is 15 - 17
