[ARCHIVED] Traffic Alert: Multi-Day Detour Scheduled for NB I-81 in Montgomery County

SALEM – As part of a maintenance project to rehabilitate pavement on northbound Interstate 81 between mile markers 121 and 125 in Montgomery County, a multi-day detour is scheduled to begin at 7 p.m. Sunday, April 6. The detour will be in place 24 hours a day for approximately eight consecutive days.

Traffic impacts will differ for day and nighttime traffic during the detour.

Daytime Detour
Between 6 a.m. and 10 p.m. each day, one lane of northbound I-81 will remain open for tractor-trailer traffic. All other traffic, including wide loads over 11 feet, will be detoured onto Route 11/460 at exit 118C in Christiansburg.

Nighttime Detour
From 10 p.m. until 6 a.m. each night, all northbound I-81 traffic will exit onto Route 11/460 at exit 118C in Christiansburg and return to northbound I-81 at exit 132 (Dixie Caverns).

Signs and law enforcement officers will be in place to control traffic. Drivers should allow additional time to reach their destinations and expect delays.

Weather and work schedule permitting, the northbound lanes will open to traffic by Monday, April 14, at 6 a.m. After this date, the contractor will resume nightly lane closures to complete the work.

If weather conditions delay the work, the contractor may extend the detour plan into the day Monday, April 14 and Tuesday, April 15.

Before the detour is activated at 7 p.m. on Sunday, April 6, mobile lane closures and short-term slow rolls may be utilized from 4 p.m. until 7 p.m. on northbound I-81 between mile markers 114 and 118 to allow the contractor to prepare the detour route.

This $6.7-million maintenance project requires the contractor to excavate deep patches before replacing layers of stone and asphalt. Additionally, this project includes drainage structures and guardrail installations.

The Virginia Department of Transportation selected a traffic plan involving a detour to shorten the overall amount of time traffic would be impacted. The other option considered would have required long-term permanent lane closures on northbound I-81 causing lengthy backups.

The project completion date is spring 2015; however, the contractor estimates that most work will be completed in fall 2014.
