As part of the ongoing road construction project to build a five-mile truck climbing lane along southbound Interstate 81 in Montgomery County between mile markers 120 and 125, southbound detours are scheduled for Sunday, July, 21 through Thursday, July 25.
Southbound I-81 will be detoured each night between 10 p.m. and 6 a.m. the following morning for paving. Traffic will be detoured at exit 132 (Dixie Caverns) onto Route 11/460 and back onto I-81 at exit 118 (Christiansburg).
Dates and times are tentative and could be adjusted due to weather or work schedule.
Signs and message boards will be in place to alert drivers to these traffic detours.
Work on the truck climbing lane project is expected to be completed in November 2013.
