Work on the project would be divided into two sections:
Watauga Bridge Replacement (Section BA)
The Watauga bridge, which carries N.C. 105 over the Watauga River north of the Broadstone Road intersection would be replaced. Construction would begin in 2019, ahead of widening N.C. 105, which is expected to begin in 2025.
N.C. 105 Widening (Section B)
Between Old Shull's Mill Road and Broadstone Road, improvements would include extending the existing passing lane further to the south, realigning a sharp turn at the southern intersection at Old Shull's Mill Road and N.C. 105 as well as closing the northern Old Shull's Mill Road and N.C. 105 intersection.
Between Broadstone Road and N.C. 105 Bypass, work would include widening the roadway to four lanes with a 23-foot wide raised grass median.
Six-foot paved shoulders would be added along the entire 4.5-mile corridor. The shoulder widths and retaining wall heights would vary along the corridor depending on how steep the mountain is in a particular area.
