Shirley Contracting Company, LLC; Clark Construction Group, LLC; Guy F. Atkinson Construction, LLC; Trumbull Corp; and Facchina Construction Company, Inc. were the lead contractors and joint venture members of ICC Constructors (IC3)—with Dewberry as the Lead Designer. This joint venture designed and built a new 3.8-mile six-lane variable rate toll road (from west of US 29 to east of I-95), two miles of collector-distributor roadways, a three-level interchange with US 29, a new interchange with Briggs Chaney Road, and a three-level interchange with I-95. The construction included 25 new bridges with aesthetic elements to complement the surrounding area, more than two miles of sound wall barriers, and over two million cubic yards of earthwork.

The IC3 team was responsible for bridge and structure design and construction, environmental services, floodplain and stormwater management, multiple jurisdiction involvement, and maintenance of traffic on I-95 and US 29. The project included a significant commitment to limit environmental impacts to the surrounding communities and area—including Little Branch Stream Valley Park and Fairland Regional Park. An Environmental Compliance Plan, which was developed and managed by the IC3 team, ensured we minimized impacts to forest, cultural resources, parklands, wildlife, wetlands, and waterways. The IC3 team successfully achieved the prescribed environmental requirements and goals—earning several quarterly environmental incentives.

Additionally, the Team was responsible for the Project’s QA/QC implementation and conformance. A specific project QC Program was approved and implemented.

I believe that this project stands out as a safety success story. It can be counted as a success that each worker went home every day to family and friends. Each of you—your management and your employees—contributed to the on-time project completion with an outstanding safety record.
