Project Title: Forest Diversion Proposal of “Rehabilitation and Up-gradation of Ratnagiri Kolhapur Section of NH-166 from existing km 31/000 (Pali) to km 76/600 (Amba) [Design km.31.000 to km. 73.430] to Four lane with paved shoulders & improvement to existing Amba Ghat section from km 71/500 to km 76/600 in the state of Maharashtra on Engineering, Procurement & Construction (EPC) Basis Contract” The maximum length of the Project Road passes through hilly terrain and at few places passes through plain and rolling terrain. At very few places exposed hard strata is found and maximum length passes through Murrum strata. In most of the length One-side valley and other side hill are located. Amba Ghat between Km. 62.00 & Km. 74.00 is major hilly portion having acute curves / hair pin bends & steep ascend & descent for improvement requiring major realignments & in part length from km 70 to 74 Tunnel is necessary for development, other Ghat portions are Dabhole between km 46 to km 56 & Panhala km 119 to km 123. Entire road is in half cutting & half banking and cut material is utilized on valley side for getting formation. 3. Homogenous Section The 126.085 km long project road is divided into four homogeneous sections [HS]. The start & end km, length of HS in each is shown below Table 1.1.

Draft Detailed Project Report For Draft Detailed Project Report preparation the Project road is divided in following sections: 1. Section I: km 0/000 to km 19/800 – Mirya to Hathkhamba Junction, Length = 19.800 km 2. Section II: km 31/000 to km 76/600 – Pali to Amba including improvement of existing Amba Ghat from km 71/500 to km 76/600, Length = 45.600 + 5.100 = 50.700 km Project Title: Forest Diversion Proposal of “Rehabilitation and Up-gradation of Ratnagiri Kolhapur Section of NH-166 from existing km 31/000 (Pali) to km 76/600 (Amba) [Design km.31.000 to km. 73.430] to Four lane with paved shoulders & improvement to existing Amba Ghat section from km 71/500 to km 76/600 in the state of Maharashtra on Engineering, Procurement & Construction (EPC) Basis Contract” 3. Section III: km 76/600 to km 137/285 – Amba to Kolhapur including New Kolhapur Bypass upto Miraj Solapur NH-204, Length = 60.685 + 9.000 = 69.685 km This report deals with Section II from km 31/000 to km 76/600 – Pali to Amba including improvement of existing Amba Ghat from km 71/500 to km 76/600, Length = 45.600 + 5.100 = 50.700 km 5. Improvement Scheme The improvement proposal consist of improvement to existing carriageway by strengthening/widening (concentric & eccentric)/reconstruction/new construction to two/four lane with paved shoulders. The improvement proposal includes improvement to geometrically deficient curves and grades to meet the geometrical standards by realignments, New Bypasses to conjusted towns/villages. New construction of Tunnel, New construction of grade separated structures Flyovers, VUP, PUP & service roads etc. All submersible minor and major bridges are proposed for reconstruction / widening / new construction as per standards of MoRTH. It is also proposed to reconstruction / widened / new constructed the Hume Pipe Culverts / Slab drains to meet the National Highway standards. The improvement scheme relates to km 31/000 (Pali) to km 76/600 (Amba) The existing length of project road section is 45.600 km & design length is 42.430km & improvement to existing Amba Ghat section from km 71/500 to km 76/600 is also included in the project road development. Total Lengt : 42.430 + 5.100 = 47.530 km. Table 1.2 : Total Length of project road.
