U.S Route 121 and U.S Route 460 Connector Phase II entails the new construction of approximately 56.25 miles of four-lane limited access highway in southwestern Virginia. These design-build and public-private-partnership projects involve the preliminary engineering, design, and construction of two high-priority corridors through the Appalachian Region of Southwest Virginia. When completed, U.S. 121 will connect Interstates 64 and 77 in West Virginia to Route 23 in Virginia. U.S. Route 121 is developed in multiple phases as funding permits. U.S Route 460 Connector Phase II will connect to U.S Route 121 near Grundy, VA and the U.S Route 460 Connector Phase I project near the Kentucky state line. RS&H, working as a subconsultant, has provided a variety of services to VDOT related to project management and project controls.
