Mizoram State Road-II CHAPTER -1 INTRODUCTION 1.1 Background: Mizoram State Road Project II The “seven sisters” of North eastern India are landlocked states and lag significantly behind the rest of India in terms of income and human development indicators. The State of Mizoram, bordering Bangladesh and Myanmar, is among the poorest states in India. Recognizing the need to share prosperity and promote growth in lagging states, the Government of India in its 2012 budget speech, committed to significant investments in infrastructure development and trade promotion for lagging states, including the landlocked states of the Northeast. In this context, The Government of India has requested World Bank for financing rehabilitation, widening and strengthening of State Highways and District Roads which are managed by Public Works Department (PWD) in the State of Mizoram. The proposed improvements are expected to enhance the quality of service level. In line with this request, Mizoram State Roads Project – II (MSRP II) is proposed. The proposed roads under MSRP II is shown in Figure 1.1 PWD Mizoram 1 EIA of Champhai- Zokhawthar Road Mizoram State Road-II G Junction NH44A (Origination) – R Chungtlang – Darlung – Buarpui O U G P R - Buarpui – Thenlum – Zawlpui O 2 U R P O Zawlpui – - A Phairuangkai 1 D R S Champhai – Zokhawthar O Lunglei - Tlabung - Kawrpuichhuah A D S Chawngte including bridge to Bungtlang South up to Multimodal Road junction Chhumkhum-Chawngte Figure 1-1 Map showing the proposed road under MSRP II PWD Mizoram 2 EIA of Champhai- Zokhawthar Road Mizoram State Road-II 1.2 Project Objective, Location and Scope The Mizoram State Roads Project II (MSRP-II) key objective is to improve existing road connectivity through rehabilitation, strengthening and widening efforts. Such an effort would also lead to incidental benefits of improving the quality of existing connectivity to Bangladesh and Myanmar. As part of the project preparation, about 157 km of existing road length, under Group 1 will be strengthened and upgraded, as they are already designed; and as part of project implementation, design additional 284 km of existing roads under Group 2 for upgradation.
