IC3, A Joint Venture of Shirley Contracting Company, LLC, Clark Civil, Facchina Construction
Company and Trumbull Corporattion was formed as the design-build team for Contract
D/E (fi nal phases) of the Intercounty Connector (ICC). The $100 million Contract includes
construction of approximately 0.9 miles of tolled roadway with interchanges at Virginia
Manor Road and U.S. 1, and 2.4 miles of new collector distributor roads adjacent to the north
and south bound lanes of I-95. The scope of work also includes 0.7 miles of improvements
to U.S. 1 and 2.4 miles of resurfacing on I-95. The Intercounty Connector Contract D/E will
complete the 18.8 mile highway that connects I-270/I-370 in Montgomery County to I-95/
U.S. 1 in Prince George’s County. IC3 completed Contract C in November 2011.

While comprised predominantly of new highway construction, the project includes
wetlands, stormwater management, and environmental features along the frontage of
a major development called Konterra and communities along MD 198. Environmental
features within the Contract include stormwater management ponds adjacent to I-95,
Bio Retention Basins and Ditches, Bear Branch stream and MD 198, and sound wall
reconstruction and retaining wall construction in the area of the MD 198 interchange. One
new bridge will also be built on Virginia Manor Road crossing over ICC (MD 200) as part
of the interchange to aid in servicing the local community with access to and from the toll
road.

To minimize community impacts, major eff ort will be made to ensure work schedules, noise,
dust, haul routes, maintenance of vehicular and pedestrian traffi c, staging areas, retaining
walls and employee parking are developed in keeping the quality of life of the of local
communities. Additionally, several visual cues will alert motorists that the six-lane highway
is transitioning to the four-lane boulevard and fi nally to a signalized intersection. These
include reduced design speeds, adding curbs and gutters, denser and more formalized
landscaping and lighting.
