Typical Cross Section Description:
Proposed 2 lane partially divided highway; 2 paved lanes (total 24' wide), 8' shoulder on
each side (11' with guardrail). Varying fill and cut slopes (see project XSC's for detailed
information). 3 lane portions along the project with painted/striped medians and new turn
lanes. Realignement of multiple curves and grades for better site distances.
Existing 2 lane, open shoulder highway; 11' lanes, 2' shoulders on each side (wider in
locations with guardrail). Steep grades and tight curves (with poor sight lines).
Annual Avg Daily Traffic (veh/hr/day):
Design/Future: 11,122 Year: 2050

General Project Narrative:
(Description of Minimization of Water
Quality Impacts)
The widening of US 19/129 from the Georgia State line to US 64/74 will involve grading, paving, widening, drainage improvements (including culverts), signing, signals and utility
work. This project will have an updgraded signalized intersection with US 64/74 and median/dedicated turn lanes at the intersections with almost all Y lines (Jim Cordell Rd,
Moccasin Creek Rd, Martins Creek Rd, Mountain Willow Rd, Price Weaver Rd, Lance Rd, Taylor Hensen Rd, and US 64/74). There are two proposed major structures along
the project; an extended existing 8'x8' double barreled culvert with a proposed 72" overflow pipe conveying Cobb Creek, and a new 8'x9' single barreled culvert conveying Gold
Branch Creek. Where excavation is necessary, coir fiber matting and rip -rap were utilized for bank stabilization in an attempt to reduce sediment transport and streambank
erosion. Measures have been taken, including reduction of pipe slopes & energy riffles in channel changes, to lower velocities at jurisdictional features to non -erosive. In an
effort to minimize impacts to the project, the team used 2:1 side slopes with guardrail in stream areas where feasible. All of the design is within the Hiwassee River Basin.
