s may be called a truck route. If there are no strong land use controls, buildings are often built in town along a bypass, converting it into an ordinary town road, and the bypass may eventually become as congested as the local streets it was intended to avoid. Many businesses are often built there for ease of access, while homes are often avoided for noise and pollution reasons. Bypass routes are often on new land where no road originally existed. This creates a conflict between those who support a bypass to reduce congestion in a built-up area and/or as replacement for roads that became obsolete and inactive because devastating natural disasters — those who oppose the development of (often rural) undeveloped land. A city may also oppose the project, because of the potential reduction in city core. For other reasons (e.g. natural disasters), construction of bypass routes may be started if there was a research about natural disaster green (safe) zones using space satellite-based mapping first before building them.
