Draft Environmental Impact Assessment Report - Meghalaya State ...

Description of the ProjectThe improvement works will also provide service areas at regular intervals for thehighway users and therefore the current practice of stopping vehicles near theurban/congested stretches will be relatively unhindered. The impacts on air andnoise due to traffic congestion/hindrances will also be removed as compared tothe present situation.The options of concentric widening and left or right side widening have beenconsidered for the improvement project so as to utilize the existing right-of-way(ROW) as far as possible and minimize acquisition of additional land. However,land acquisition will be required as the existing ROW varies between 10 m to12m.Table 2.3: Project InterventionsSl.no Features Existing Proposed1 Right of way 10 to 12m in hillyterrain; 15 to 17m inrolling2 Carriageway 2- lane carriagewaywith width of 6.45 to8.3m.20m2- lane carriageway of 7m with 1m pavedshoulder on hill side and 1.5m paved plus0.5m granular shoulder on valley side.Junctions Minor-29 Up-gradation3 Bridges:Major4 1 reconstruction;3 repairedMinor 35 1 reconstruction34 to be repaired4 Culverts :Pipe5 Slab/ RCCslab50 10 to be reconstructed40 to be repaired391 85 to be reconstructed306 to be repaired6DrainageMasonry drain –68.716 kmUnlined drain -74.8 kmStone masonry drain -3.36km7 SlopeprotectionMasonry retainingwall- 11.59km,Breast wall- 501mGabion wall - 57.5mlengthRetaining walls and breast walls-20.49 km (2 to 7m ht.)Extension of 5m wall- 4.63 kmGabion wall of 2m ht- 2.98 kmGabion wall at slope protection work-385m3.06 km by installing synthetic erosioncontrol mat etc. and rock bolts.
