RSA was the surveying subconsultant for the design on this section of the Route 58 Corridor Development Program.  Project surveying services performed include the following:

• All Global Positioning System (GPS) surveying services related to control adjacent to proposed highway route; 
• Monumentation and photo control for aerial photography;
• All conventional, base line, horizontal and vertical control surveying services related to preparation and augmentation of topographic mapping of proposed highway route (mapping in Microstation digital format and ink-on-mylar format);
• Property and utility research, property surveys; and
• Preparation of base work sheets, supplemental DTMs, detail sheets, and acquisition plats.

Clarksville Bypass 

The 5.3-mile-long Clarksville Bypass includes 11 bridges, including a 4,800-foot-long bridge over the John H. Kerr Reservoir (also known as Buggs Island Lake), a 492-foot-long bridge over the Clarksville small boat harbor, and twin bridges over the Occoneechee Harbor (Sandy Creek). The bypass passes just south of the town limits of Clarksville, and it is a 4-lane limited access highway, with interchanges at US-15 south of Clarksville and US-15 east of Clarksville, and two other at-grade intersections. The bypass carries US-58 and VA-49 along its whole length. Each transition from existing US-58 to the new bypass forms a continuous seamless highway from existing to new, with the existing highway being connected to the new via a T-intersection west of the town, and east of the town via a directional interchange that includes a flyover for westbound traffic. The project includes 1.0 mile of 4-lane reconstruction of US-58 west of the west end of the bypass, and 0.7 mile of 4-lane dualization east of the east end of the bypass, for a total project length of 7.0 miles.
