When addressing a congestion or safety problem within a town or city, often a bypass is considered as an alternate.  Planners and designers must carefully weigh the community impacts that will be caused when considering a bypass.  Some considerations include:

• Level of access control and impact on traffic flow
• Location of bypass relative to central business district and impact on employment growth
• Expected impact of new and/or relocated economic activity and employment
• Impact of bypass on green space and working farmland
