Abstract: Environmental impact assessment (EIA) for transportation projects has an integral role in environmental management schemes. All the road works and other transportation infrastructure development programs creates significant impact on various aspects of life. Impacts can be positive or negative. Here an EIA is conducted to study the socio-economic impacts and bio-physical impacts of widening of Thrissur – Vadanapally road project and evaluation of the same. The impact prediction is done by means of good fit models for the existing conditions. Gaussian air dispersion model, CRTN Model for traffic noise, Mass Balance and Streeter- Phelps Equation for water quality analysis were used. With the help of these models, the prediction is done accurately. The predicted impact includes the meteorological and climatic impacts, noise quality, water quality, air quality and social impacts. Water quality changes rises only when there is change in drainage pattern occurs. These change is modelled using the Streeter Phelps equation and the mass balance equations. Air quality modelling was done using the Gaussian dispersion model and the impact of traffic noise was done using the CRTN Models. The air and noise values at the present condition was greater than the prescribed norms of pollution control board. The air quality issues are predominant at distances nearer to the source, as the distance increases the effect of air pollution also decreases. Various mitigation measures are suggested for reducing the impacts predicted or to avoid the impact in each stage of construction.
