In 1996, the North Carolina Department of Transportation (NCDOT) and Ko & Associates completed the environmental planning documents and functional/ preliminary designs for a nine-mile portion of US 311 in Randolph County between Archdale and Randleman, NC. This proposed new location freeway, estimated at nearly $90 million, is the final link in completing a freeway system from US 311 from I-40 at Winston-Salem to US 220 near Randleman.

The Environmental Assessment and a Finding of No Significant Impact evaluated the environmental effects of three alternative freeway locations. The recommended alternative weighed the engineering design criteria, costs, and environmental effects.
Ko & Associates worked with NCDOT to plan and design cost-effective solutions for the proposed freeway that avoided and minimized effects, to the extent possible, on the human and natural environment. Important engineering and environmental planning efforts included:
|
Natural Resource investigations to determine potential effects on streams, wetlands, the proposed Randleman Reservoir watershed, and federally protected species
- A comprehensive public involvement program that included public workshops, newsletters, small group meetings, and hearings
- Cultural resources investigations to identify potential historic and archaeological sites
- Traffic Capacity, Traffic Noise, and Air Quality Studies
- Evaluation of social and economic effects on communities
- Development of functional and preliminary roadway and interchange designs
- Preliminary hydraulic design studies
