TIP Project No.: R-2566B
WBS No.: 37512.1.1
The Project Team has concurred on this date to use the following measures to minimize or avoid impacts.
The typical section varies along the project corridor, and was selected so that the project would meet the
purpose and need of the project with the minimal footprint feasible. Of the 5.5-mile corridor studied,�c�cree��
e��ese� �� �� 1.7 miles of 3-lane road, 2.8 miles of 4-lane divided road, and 1 mile with no improvements.
In addition, the following avoidance and minimization measures were included in the design:
Selected a best-fit alignment that minimizes impacts to Watauga River, Laurel Fork, and Big
Branch, including widening asymmetrically in several locations.
Added several retaining walls and concrete barriers to further reduce impacts to streams.
Used steeper slopes to minimize or a�oid impacts in several locations.
