INTRODUCTION 1. This summary environmental impact assessment is based on three environmental assessment reports for the proposed Subregional Transport Connectivity Project (the Project) in India. These reports were (i) the initial environmental examination (IEE) of the proposed rehabilitation and improvement of Baharampur and Maldah bridges; (ii) the IEE of the proposed rehabilitation and improvement of the road connecting Fulbari (on the border of India and Bangladesh) to Panitanki (next to Kakarbhitta in Nepal), and the road connecting Hasimara (in India) to Jaigaon (next to Phuentsholing in Bhutan); and (iii) the environmental impact assessment (EIA) of the proposed rehabilitation and improvement of national highways (NH) connecting Raiganj to Dalkhola and Sevok to Gangtok, as well as the construction of two bypasses in Dalkhola and Barasat in West Bengal Province. In addition, this summary took into account the reports of the rapid wildlife movement assessment that was carried out in Mahananda Wildlife Sanctuary (MWS) area and Raiganj Wildlife Sanctuary (RWS). 2. The Project initially was categorized as a “B” project, according to the Asian Development Bank’s (ADB) Environmental Assessment Guidelines of 2003. However, the environmental survey found that the Raiganj–Dalkhola and Sevok–Gangtok stretches pass through designated wildlife sanctuaries, and that the Barasat Bypass will require new construction. Based on these findings, these three subprojects were reclassified as “A” projects. Subsequently, EIAs for these subprojects were prepared. 3. The environmental assessment studies were carried out between August and December 2004. The technical assistance (TA) consultant prepared the IEE and EIA reports on behalf of the state Government of West Bengal (SGWB), state Government of Sikkim (SGS), and Ministry of Shipping, Road Transport and Highways (MOSRTH). 4. These EIA studies were based primarily on secondary data. The environmental study covered the project area, as well as the area of direct and indirect impacts. These environmental assessment reports were prepared in accordance with relevant laws and regulations of the Government of India; and with the Environmental Policy of the Asian Development Bank, 2002 and the Environmental Assessment Guidelines of the Asian Development Bank, 2003.1 II. DESCRIPTION OF THE PROJECT A. Location of the Projects 5. Six of the seven subprojects proposed under TA 6154-REG are in the state of West Bengal. The other one (the Sevok–Gangtok road subproject) passes through two states, Sikkim and West Bengal. Table 1 provides the location of each subproject.

B. Need for the Projects 6. The Project is needed primarily to improve connectivity within northeastern India and with neighboring countries, especially Bangladesh, Bhutan, and Nepal. Brief explanations of the need for each subproject are provided in paras. 7–14. 1. Barasat Bypass 7. Nepal, Bhutan, and Bangladesh are connected with Kolkata Port through NH 34 and NH 35. Intense urban development has caused congestion on many parts of these highways. Barasat town, which is part of greater Kolkata, is expanding quickly. In addition, the Belgharia Expressway and the second Vivekananda Bridge will increase traffic flowing from NH 2 and NH 6 directly into NH 34 and NH 35, congesting traffic in Barasat town. Therefore, NH 34 traffic should bypass Barasat Town in the future. 2. Raiganj–Dalkhola 8. The development of NH 34 from Kolkata (beyond Barasat) to Raiganj is covered by the ADB-funded West Bengal Corridor Development Project. However, the Raiganj–Dalkhola section of NH 34 was not included for improvement under that project. The condition of the Raiganj–Dalkhola stretch has deteriorated seriously. Rain seepage and water accumulation in potholes have weakened the road’s foundation. 9. Dalkhola town is on the northern end of NH 34, where the highway joins NH 31—the main east-west corridor from Gujarat in the west to Assam in the east. NH 34 passes through the main part of Dalkhola town, which is heavily congested already. Therefore, the town should be bypassed. 3. Sevok–Gangtok 10. Since this is the only road connecting the state of Sikkim and its capital Gangtok with the rest of the country, it is considered the lifeline of Sikkim. However, the road is narrow (1.5 lanes), has many hairpin turns, and is congested during the tourist months. Many areas are prone to landslides, and maintenance costs are high. Improving this road would strengthen Sikkim’s connection with the rest of the country. 3 4. Hasimara–Jaigaon 11. The Hasimara–Jaigaon stretch is Bhutan’s most important road link with India. It is used for most of Bhutan’s trade with India and other countries. Traffic is expected to increase substantially over time, which will require a capacity expansion. 5. Panitanki–Fulbari 12. The Panitanki-Fulbari stretch is an important interregional link between Nepal () and Bangladesh (Fulbari) through India.
