KM-3/4 to 192/4-NH-12A Jabalpur-Mandla-Chilpi Road Justification of the Project 1.1 General National Highway No-12A, highway start from Jabalpur runs via Barela, Udaipur, Bijadandi, Mandla, Madhopur, Anjania, and Bichhiya in Madhya Pradesh. Its connect NH-12, NH-7, NH-43 and NH-200. This is officially listed as running over 280 km from Jabalpur in Madhya Pradesh to Simga in Chhattisgarh. The projects road also passes through Kanha National Park ,which is Famous National park in india and after construction of the road traffic will increase. The project section of NH-12A it covers three districts of Madhya Pradesh i.e., Jabalpur, Mandla & some portion of Balaghat. It starts from km 3/4 as mentioned in, and ends at km 192/4. The total length of the section is 189 km.The present stretch is generally 2-lane with earthen shoulder. The Project Road section is in rolling and hilly terrain. There are sections in cutting and embankment. Thus the embankment height is varying from very high to almost flat at some stretches. Poor drainage condition leading to pavement distress has been observed at sections. The height of embankments at bridge approaches from 2.00 m to 4.00 m. From visual observation the sub grade soil is observed as Medium Black Soil for almost the entire stretch. Except at few stretches where granular soils were also noticed. The Project Road passes through fairly populated area of Jabalpur, Barela, Udaipur, Bijadandi, Mandla, Madhopur, Anjania and Bichhia. It is proposed to develop the Project Road as Two Lane with paved shoulder. Latitude and longitude of the project corridor lies between 23° 09' 48” N (Jabalpur) to 22º 35’ 55”N (Mandla), 21° 22' 45” N (Chilpi) and 79° 56' 41” E (Jabalpur) to 80º 22’ 14”E (Mandla), 81º 04’ 10” E (Chilpi) respectively. 2.2 Terrain Classification of terrain (Table 2.1) Hill Terrain Rolling Terrain Plain Terrain Km 19- km 22 km 3/4- km 19 Km 23- km 25 Km 22- km 23 Km 27- km 28 Km25 - km 27 Km 32- km 34 Km 28 - km 32 Km 36- km 39 Km 34 - km 36 Km 40- km 45 Km 39- km 40 Km 46- km 51 Km 45- km 46 Km 58- km 65 Km 51 - km 58 NIL Km 67- km 69 Km 65 - km 67 Km 70- km 76 Km 69 - km 70 Km 80- km 81 Km 76 - km 80 Km 125- km 127 Km 81 - km 125 Km 133- km 134 Km 127 - km 133 Km 142- km 143 Km 134-Km142 Km 165- km 166 Km 143- km 165 Km168 - km 169 Km 166- km 168 M.P.Road Development Corporation Ltd.

This is due to extension of Jabalpur town. There after the Project road passes through generally agricultural and forest areas. Patches of village town exist along the Project Road. The details of Land Use are presented in Table 2.2. Land Use Pattern along the Project Corridor (Table 2.2) Some of the section of the alignment is passing through forest area having some reserve forest also. So broadly forest and non-forest area identified and tabulated as under. A Jabalpur Municipal limit is densely built-up along the road and the other township along the road is Barela, Udaipur, Bijadandi, Mandla, Madhopur, Anjania & Bichhiya. Mandla is also a district headquarter. Summary of Land use pattern Table 2.3 Description Length in Km % Urban limits 27.200 km 14 Semi Urban limits 23.400km 12 Forest limits 53.800km 29 Agriculture limits 84.600 km 45 Total limits 189.000 km 100 2.4 Right of way (ROW) Due to presence of various types of land use along the Project Road, the ROW varies widely. The ROW is significantly low near the forest areas. However an average ROW width of 30m is generally M.P.Road Development Corporation Ltd. KM-3/4 to 192/4-NH-12A Jabalpur-Mandla-Chilpi Road available. Apart from requirement of geometric improvement, this ROW width is sufficient to accommodate the hard and paved shoulder. The available ROW width is presented in Table 2.4. 2.5 Carriageway and Shoulder width The existing carriageway is generally 7.0m wide with earthen shoulders on both sides. The earthen shoulders are of varying width. The details are presented in Table 2.5. The Table also indicates the average height of embankment and depth of cutting. 2.6 Culverts and Bridges There are 361 culverts, 7 major bridges and 39 minor bridges along the project Road. The culverts are of stone arch, brick arch, slab and pipes. Most of these are old, narrow, weak and distressed. Out of 361 culverts, 244 are pipe culverts and 117 are box and slab culverts. However some of these are relatively new. Most of the culverts require widening to National Highway Standards or replacement. The summary of existing Bridges is presented in Table 2.6. The proposal of re- construction; widening and new construction of culverts is presented in Chp-4. Detail of existing 2.7 Junctions and Intersections. There are total 109 road junctions. The junctions are mainly with village roads. There are junctions with NH, SH, MDR and ODR as well. The list of all road junctions is indicted in Table 2.7. The summary of road junctions is as follows: National Highways (NH) : Nil State Highways (SH) : 5 Major District Road (MDR) : 9 Other District Road (ODR) : 5 Village roads (VR) : 90 7 of the major junctions and 12 minor junctions. Details proposal have been given in Chapter 4: Improvement Proposals.
