New road construction
Taxonomy and descriptionIntroduction and Terminology Road construction or road building covers a range from creation of entirely new roads reaching places where no road access previously existed, through bypasses to relieve sensitive areas, to intensification of the road network, and widening of existing roads in order to increase capacity. Road construction is not here taken to mean re-configuration of existing roads (for instance, to straighten bends) since this can involve very different purposes and problems. Construction of cycle routes and pedestrian areas are covered elsewhere. The following description will consider roads intended for use by motor vehicles as well (often) as other users. Description Road construction can take ostensibly straightforward aims of providing access to areas previously inaccessible by motor vehicle, reducing traffic volume in one area by moving it to another, or of increasing capacity. Yet each of these aims can result from many, complex motivations.
