ICC - The Intercounty Connector

Maryland Begins to Build a New Highway

By Rachel Cooper, About.com


The federal government has approved the $2.4 billion construction of the ICC, the Intercounty Connector, in suburban Maryland north of Washington, DC. The ICC will be an 18-mile highway linking Interstates 270 and 95 providing easier access from Montgomery to Prince George’s Counties. The six-lane highway will have nine interchanges and one intersection. Construction of the ICC began in 2007 and is projected to be completed in 2011.

The ICC has been on the plans for more than 50 years. Building the ICC was a hotly debated project and was opposed by community groups and environmentalists. A study was conducted examining the transportation needs of the area and the environmental impact of the construction of a new road throughout the years. The Intercounty Connector Study was completed by the Maryland State Highway Administration (SHA), the Maryland Transportation Authority (MdTA) and the Federal Highway Administration (FHWA). The study was coordinated with Montgomery County, Prince George's County, the Metropolitan Washington Council of Governments, and the Maryland National Capital Park and Planning Commission.

Maryland Governor Robert L. Ehrlich Jr. and Montgomery County Executive Douglas M. Duncan were both instrumental in gaining approval for the construction of the new road. They developed support for the project by showing that building the ICC will create job opportunities and provide better access to employment around the region. The ICC will also improve homeland security by providing an additional evacuation route.

The ICC is a multi-year project and is being built in five sections.
