I d e n t i f 4. i Identificationc of Alternate a t i o n o f A l t e r n a t e R o u t Routese s 4.1 APPROACH METHODOLOGY he purpose of this report is to design a socio-economically acceptable route for the project corridor, utilizing the available maps, imageries, conduct the field reconnaissance & surveys and consultations along the project route which fulfils the intended T purpose of implementing agency towards the facilitation of transport communication, promote socio-economic development & economic growth and reducing poverty. Also such a route should have the least negative impacts on the environment and should also be protected from the negative effects that may be caused by the surrounding environment. The project road from Malerkotla- Lehra-Moonak-Uklana has been constructed long ago and rehabilitated several time, and currently also going under maintenace contract, and serving the minimal purpose of local people and there is no complaint against the existing road alignment,except at some bottle neck points, which reveals from the road side interview. It is worthy to mention here that “when the road is planned for further upgradation (as the case from 2 to 4/6 lane), it becomes very important to study the superiority of alternates, to improve the geometry”, however, even the project road under study does have the well define existing road, consultant critically studied the existing alignment and where felt mandatory to realign the route, taken into consideration the alternates for further study. Route options for a designated highway are defined as approximate alignments within the route corridor that are compared in order to select the preferred route. The IRC SP19-2001, Manual for Survey, Investgation and Preparation of Road Projects lays out general considerations and best practice with regard to route selection. These include: The fundamental principal of route selection and alignment improvement is to achieve the least overall cost on transportation, having regard to the cost of initial construction of the highway facility, its maintenance and road user cost, while at the same time, satisfying the social and environmental requirements. Consultants are usually required to identify at least two possible alignment options, which satisfy the requirements of connecting the stated start and end points via specified control points, as well as satisfying the required geometric design standards and selected realignments may be appropriate to improve the localized geometric deficiency and, other than these cases, more than one route should be examined. In order to identify the stretches where there is no need to divert from the existing track and the stretches where alternate route is require, select the best route. Consultant has delineated the entire project route into following homogeneous section for identifications- 4-1 ALIGNMENT REPORT Consultancy Services for development of Economic Corridors, Inter-Corridors, Feeder Routes and Coastal Road primarily to improve freight movement in the India under Bharatmala Pariyojna (Lot- 2/Punjab/Package-2) Terrain Land Use Soil Type Urban Settlements Traffic Flow Geometry of existing route Drainage River Crossing Lack of ROW Realignment to cater local traffic and OD Points Realignment due to changes in local network or surrounding network Poor Road Geomtery Provisions of ROB, flyovers and other structures 4.2 ECONOMIC CORRIDOR (MALERKOTLA-LEHRAGAGA-MOONAK- UKLANA MANDI) After the delineation of homogeneous section, each section has been critically evaluated to identify the probable locations of alternate route. If alternate route is require in any homogeneous section then further extensive study has been carried out to evaluate the best alternate on the basis of Social, Environmental, Engineering and Economic analysis. The details of each homogeneous section presented in Table below.

Key Points for New Proposed Bypass: Lack of Row Built up section New Alignment to cater Local Traffic and OD Points The main reason to join the proposed bypass near village Boghiwal on Ludhiana – Malerkotla road is that as the project road is part of Ludhiana-Ajmer Economic Corridor, which will cater the traffic. On proposed bypass side, the project road will pass through SH51 (Malerkotla-Nabha) i.e. will also cater traffic from other surrounding districts to the economic corridor.

There is the homogeneity of geology, land use and land cover along the section. Key Points for New Proposed Bypass: Option-1 Lack of Row Built up section (Proposed Bypass) New Alignment to cater Local Traffic and OD Points The main preferred option-1 is passing Option-2 totally through greenfield land, and not (Proposed Bypass affecting any built up section , as the case in Option-2, although ROB is same in both options.
