The new City Line Road interchange will deliver long-awaited and much needed relief for heavy traffic volumes at two current I-64 interchanges, Greenbrier Parkway in Chesapeake and Indian River Road in Virginia Beach as well as on other thoroughfares south of the interstate. The additional infrastructure is projected to reduce vehicular activity by 17% at the Indian River Road/I-64 exit and by up to 15% at the Greenbrier/I-64 interchange

The need for this new infrastructure was first cited in a 1999 study prepared for the Virginia Department of Transportation, which said that City Line Road was needed to:

•	Address deficiencies in the existing regional road network.
•	Preserve and enhance the commercial viability of the Indian River Road, Greenbrier Parkway and Battlefield Boulevard corridors
•	Improve the area’s transportation system in accordance with regional transportation plans
•	Provide transportation facilities to support ongoing population growth and development in Virginia Beach and Chesapeake
•	Create an additional access point to I-64

The study and results were not motivated by any proposed development by CBN. In fact initial opposition by CBN caused the project to be stopped.

Today City Line Road and the proposed interchange have the support of the localities, the federal and state governments as well as the Metropolitan Planning Organization.

CBN has insisted that a transportation solution be identified and approved before construction of Blenheim because burdening existing roadways are not adequate to handle expected traffic volumes.

85% of the costs of the interchange and City Line Road will be financed through increases in property tax revenue generated on the site. None of the responsibility for repayment of bonds used to construct the road improvements will fall upon local taxpayers; rather they will be borne by the developers.
