OVERVIEW The Mizorom State Roads Project (MSRP) is being prepared and implemented by the Mizoram Public Works Department (MPWD) with World Bank (WB) assistance. Phase I of the project is under construction following appraisal by the Bcnk in 2002. The project preparation for Phase ll is underway since fate 2001. A consortium], acting as Project Co-ordinating Consultants (PCC). is assisting the MPWD during- project preparation. Their inputs will continue (in 1imited capacities) throughout the project duration. in addition, MPWD will also hire the services of a Construction Supervision Consultant as the Engineer for the implementation along similar lines as Phase 1. Like all Category 'A' transport projects funded by the World Bank, MSRP is subject to an lndependent Environmental Review2. This Environmental Impact Assessment and its companion reports, covering the activities to be carried out in Phase 11,have been scrutinized during the IER. These reports are now updated addressing the observations made during the Review. 1.2. PHASE tl ACTIVITIES IN MSRP Phase 11of MSRP endeavours to complete the enhanced connectivity of two of the most important cities in Mizoram - Aizawl and Lunglei, initiated in Phase 1.Upgradation of the MPWD's old Aizowl - Lunglei road will reduce the distance by 65km when compared to NH 54. A new alignment bypassing Aizawl city from the east will connect NH 54 near Zemabawk to the state highway near chainage 4.5km. In addition, 230-km of existing state highways will also undergo major maintenance. Table 1-1 summarises the works to be undertaken during Phase 11of MSRP. These routes are also shown in Figure 1.1.

Major Maintenance Component As part of Phase II activities under MSRP, several existing roads are covered under the major maintenance programme. The improvement works would mainly include: * Pavement improvement treatment. * Upgrading existing earthen roads to gravel roads * Repair of bridges * Repair and / or reconstruction of culverts * Improvement of side drains * Slope protection works at potential landslide sites * Provision of important signs. like regulatory and warning signs at hazardous locations, and other design features to improve the safety and comfort of travel. Depending on the present conditions, different levels of treatment have been proposed for shorter stretches within the entire length. These are categorised as: * Category 1.: Resurfacing at locations of moderate surface distress * Category 2: Resurfacing and construction of base course over the existing pavement at locations of acute base and surface distress * Category 3: Rebuilding of pavement from subgrade upwards at locations of complete pavement failure Table 1-2 summarises the proposed improvements for the major maintenance component in Phase II of MRSP. Figure 1-1 shows the routes selected for the major maintenance component.
