Agriculture is the main land use with very few industries along project road. Commercial activities is only noted when alignment passes through settlements however no major industries are noted along project road. Major settlements along the project road are Hanur, Kaudalli, Male Mahadeshwara, Palar and Gopinatham. P a g e | 1 Brief Project Summary 9. The project road is located in plain terrain (9 km), rolling terrain (50.0 km) and hilly terrain (36 km). Out of 36.0 km of the hilly terrain, 8.4 km stretch is above 1,000 m from mean sea level. 10. Improvement Proposal Hanur to Tamil Nadu Border (65.5 km) . In Rural areas (outside Wildlife Sanctuary Area) it is proposed to strengthen and widened the existing carriageway to 7m with 1.5m paved shoulder and 1.0m / 2.0 m granular shoulder on both sides. Earthen drain shall be provided on both sides for the surface drainage. The total proposed formation width is 12m / 14 m. In Built up areas (outside Wildlife Sanctuary Area) it is proposed to strengthen and widened the existing carriageway to 4-lane divided carriageway with 2.195 m wide RCC Drain cum footpath is proposed on both sides of project road. The total proposed formation width is 20 m . In Built up areas (outside Wildlife Sanctuary Area) it is proposed to strengthen and widened the existing carriageway to 2-lane carriageway with 2.0 m paved shoulder and 2.5 m drain cum footpath on both sides of project road. The total proposed formation width is 16 m . In Wild Life Sanctuary area it is proposed to strengthen the existing carriageway and retaining the existing alignment and formation width. It is also proposed to improve the existing earthen shoulder into hard shoulder by providing Interlocking Cement Concrete tiles within existing ROW. Apart from above it is proposed to provide W-Beam Crash Barrier on Valley side wherever the existing parapet wall is damaged or not available at site. Only 3 minor bridges are to be reconstructed without widening inside Wildlife Sanctuary Area as the existing condition of the bridges are very poor and hydrologically inadequate. Bypass / Realignment: To minimize social impacts and to improve the existing geometry of the road, bypass / realignment is proposed at 2 locations: a) Kaudalli bypass – length: 3.365 Km b) Realignment near Elemera village – Length: 0.530 km These bypasses/ realignments are outside the Wildlife Sanctuary area . Road Intersections: There are 7 major roads (3 in outside sanctuary area and 4 inside the sanctuary area) and 19 minor road/village roads (16 in outside sanctuary area and 3 inside the sanctuary area) connecting the project road. All the junctions outside the sanctuary area have been proposed for improvement as per IRC guidelines and junctions inside the sanctuary area will be improved within the available ROW without disturbing the existing trees, if any . Culverts: Outside Sanctuary area - 11 reconstruction and 6 new culverts are proposed. All 141 culverts located within wildlife sanctuary area will be retained without widening.

Truck Lay Byes: Truck lay byes proposed at one location on both sides out the wildlife sanctuary area Connectivity to Hoganakkal Falls i.e. Palar to Hoganakkal (29.5 km) . Improvement proposal does not include any widening or geometric improvement both Horizontal and vertical but is focused on improving riding quality by rehabilitation of the existing deteriorated pavement surface and minor repairs of safety features including adding Parapet / Railing to all Bridge structures which is currently missing (Figure-13). Apart from above, it is proposed to improve the P a g e | 2 Brief Project Summary existing earthen shoulder into hard shoulder by providing Interlocking Cement Concrete tiles which will also improve the riding quality 11. Water Requirement: Approx. 500 KLD water will be required per day during the construction period. There are good numbers of surface water body, irrigation canals along the project road. Water will be sourced from these surface water bodies / canals with due permission from concerned authorities 12. Solid Waste: The solid waste generated due to construction and allied activities would mainly consist of earth materials.
