The Maryland Intercounty Connector (ICC) is an 18-mile toll road connecting I-370 in Montgomery County to I-95 in Prince George's County, Maryland. The $2.4 billion road, also named MD-200, in suburban Maryland north of Washington, DC was opened in 2012. The small green dots on this map show the locations of the ICC exits.
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.
There are no toll booths. Tolls vary with a higher toll charged during peak hours (Monday - Friday, 6 a.m. - 9 a.m. and 4 p.m. - 7 p.m.) and a lower toll charged during off-peak and overnight hours. To travel the ICC from I-370 to US-1 drivers of cars and light trucks with E-ZPass will pay $3.86 during Peak hours, $2.98 Off-Peak and $1.23 Overnight. Drivers who do not have an E-ZPass and travel the ICC will be sent a bill in the mail and charged the Video Toll Rate which is a higher rate.

How Much Time Can You Save Using the ICC?
Travel on the ICC saves users time because they avoid traffic lights and can travel at higher speeds than on the roads that cross through Montgomery and Prince George's Counties.
A trip from Gaithersburg to Leisure World (near the intersection of Georgia Ave. and MD 28) via local roads takes up to 23 minutes during the morning rush hour. Using the ICC, a driver can travel the same distance in approximately 7 minutes, saving 16 minutes. A trip from Laurel to Gaithersburg saves a commuter more than 30 minutes on the ICC.
ICC Construction and History
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.
