This was a $464 million highway Design-Build Project. The Intercounty Connector included interchanges with MD 355, the Metro Access Spur Road and MD Route 97 Georgia Avenue. The project also included widening and rehabilitation I-370, which included five bridges, one over a railroad, and paving overlay.
The Intercounty Connector project was an extremely environmentally and community sensitive project and extensive measures were planned by the design-build team to minimize the environmental impact of this project. ICC – Contract A was the first of 5 contracts planned to create the $1.5 Billion 18.8 mile Intercounty Connector that ultimately connected the I-270 corridor in Montgomery County, MD to the I-95/US1 corridor in Prince George’s County, MD.
