Aggregation, sometimes called weighting and scaling, methods represents a technical fix to this problem. Advocates favor combing numerical values indi cative of individual impacts into a surrogate reflecting overall impact. These methods have two elements, scaling and weighting. In the ‘environmental evaluation system’, value functions have been concocted to translate the state of individual environmental parameters into arbitrary, environmental quality indices all expressed on the same scale. Environmental quality scores are multiplied by the appropriate weightings and added to give a total score of environmental quality for each option under considera tion.

Impact on physical environment Air quality and climate Certain project actions will release emissions to the atmos phere. These releases will be primarily due to fuel combustion (construction equipment, power generators, and space heating, and transportation vehicles), explosive detonation and fugitive dusk (excavation, drilling, and quarrying and crushing, wind erosion, and road dust). The key impact results from dust and emissions from heavy equipment during construction period. Following construction, these effects would return to normal (exist ing) level in the region.

The secondary reason for building a bridge can also be protection of natural area with high environmental and ecological value, which would be otherwise exposed to traffic and to all negative consequences connected with it. An important part of the primary step is an identification of the proposed location as well as the identification of alter native options. A description of technical and operational solutions has to be part of the screening stage as well as information about starting and ending date of the activity.
