Corridor PreservationCorridor Preservation• Corridor preservation is a strategy to assure that the network

of highways, roads, and streets will be available now and in the future to serve existing and future development needs. It involves application of various measures to:

– Minimize the costs of transportation improvements by early coordination with property owners and local government.

– Enhance and maintain efficient traffic flow in existing transportation corridors.

– Protect corridors from unnecessary environmental, social and economic impacts.

– Reduce the amount of developed property that needs to be purchased.
