The ICC, the Intercounty Connector, is a $2.4 billion road that opened in 2012 in suburban Maryland north of Washington, DC extending from I-370 in Montgomery County to I-95 in Prince George's County. The ICC, also named MD-200, is an 18-mile highway with nine interchanges and one intersection.

The ICC is Maryland’s first all-electronic toll road where tolls are collected at highway speeds using E-ZPass® technology, as vehicles pass beneath tolling structures. Tolls vary with a higher toll charged during peak hours and a lower toll charged during off-peak and overnight hours.

Construction of the ICC

The ICC was a multi-year project and was built in five sections. See a route map of the Intercounty Connector.

The ICC was planned for more than 50 years and was a hotly debated project that 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 would create job opportunities and provide better access to employment around the region. The ICC also improves homeland security by providing an additional evacuation route.
