Project Overview and Purpose
To improve traffic flow and reduce congestion along U.S. 321 in Caldwell and Watauga counties, the N.C. Department of Transportation is widening the highway from Blackberry Road through Blowing Rock to the Tanger Outlet Center/Possum Hollow Road.
Once complete, U.S. 321 – an important corridor linking the mountains to Charlotte and to national transportation networks – will be a multi-lane roadway from Charlotte to Boone.
Without these improvements, the forecasted traffic volume in the area will exceed the highway's capacity (and already does in some places). The number of crashes will likely rise along with the increase in traffic volume.
In addition to widening U.S. 321, improvements will increase sight distances by straightening curves, thereby providing a safer road.
