Inter-County Connector
Location Montgomery and Prince George's County, Maryland
Project Sponsor Maryland State Highway Administration (SHA)
Maryland Transportation Authority (MdTA)
Mode Toll Highway

The Intercounty Connector (ICC) is a toll highway under construction in Maryland. The road will link existing and proposed development areas between the I-270/I-370 and I-95/US 1 corridors within central and eastern Montgomery County and northwestern Prince George's County.

The finished highway will be approximately 18 miles in length, and have six lanes in total. The ICC was initially planned as spur off of the region's proposed second Beltway. The ICC project has been the focus of various studies and debates since the 1950s and finally started construction in 2007. The finished highway will have a variable tolling structure based on peak and off-peak travel times. Toll collection will be fully electronic, allowing toll collection without significant traffic delays. The road is also expected to stimulate new transit growth through the creation of additional express bus routes along the corridor.

Cost $2.566 billion (current cost to complete per the 2008 financial plan)
