U.S. Highway 12 - Morristown to Watauga



Project Summary:

This nine and one-half mile project involves the complete reconstruction of U.S. Highway 12 including the replacement of the narrow bridge one mile east of Morristown. This once narrow highway with minimal shoulders, upon completion, will have two 12-foot driving lanes along with 6-foot shoulders. The new grade line will provide travelers with improved sight distance, flatter in-slopes, and wider ditches that will allow for more snow storage capacity.

When construction crews and equipment are present during work hours, the traveling public will be guided through the project with flaggers and a pilot car. Motorists should expect delays of up to 15 minutes. Traffic speeds will also be reduced to 45 mph through the work zone.
