This was a $570 million highway Design-Build Project and extended from MD 97 to MD 29. Contract B involved seven miles of new controlled access, six-lane, tolled roadway and two interchanges. The new highway created interchanges with MD 650 New Hampshire Avenue and MD 182 Layhill Road. The work included mainline ramps, cross roads, utility relocations, bridges, retaining walls, and more.

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 – Contact B was the second 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.
