  • Abstract


    The study was conducted to investigate the potential environmental impacts of the proposed bridge during the pre-construction, construction and operation phase using the matrix method. The study also aims to formulate an environmental management plan (EMP) to minimize the probable impacts on the construction of the proposed bridge. A field mobilization was conducted in proposed project area to find out the environmental baseline (surface water, ground water, soil, sediments, air, noise and ecology) information and identification of possible impacts. The focused group discussions (FGDs), questionnaire survey (QS) and key informants interview (KII) were conducted to collect relevant information. Secondary data were also collected from different books, journals, Local Government Engineering Department (LGED), Upazila Agriculture Office (UAO), Upazila Fisheries Office (UFO) and Department of Environment (DoE). All the samples were analyzed in the laboratory of the Department of Environmental Science and Resource Management, Mawlana Bhashani Science and Technology University, Tangail-1902, Bangladesh. The study showed that the proposed bridge will be able to connect three Upazila (Nagarpur, Mirzapur and Dhamrai Upazila) directly and will be an easy communication way for local community, along with socio-economic and health facilities development. The EIA study also found major negative impacts of the study area that would be pollutions (air, surface water, ground water, sediments, noise and soil), accidents and soil erosion. The study also found that the dust and exhaust emission may have profound effect on flora, fauna, fish breeding, water flow, wastewater, solid waste from labor camp, construction waste, and noise during pre-construction, construction and operation phase. The EIA study found that possible negative impacts are considerable and the project can be implemented. The EIA study also suggested some defined EMPs that will minimize the probable adverse impacts of the bridge construction project over the Dhaleshwari River, Tangail, Bangladesh.
