I-81 bridge replacement will cause drivers to use detour for months


MONTGOMERY COUNTY, Va. – A bridge replacement project on I-81 is prompting a months-long detour in Montgomery County. 

Workers are replacing the New River Bridge at exit 105. 

Starting at 9 p.m. Friday, the northbound on-ramp at exit 105 will close for an estimated six months. A detour will be in place from Route 232 onto Rock Road to Tyler Avenue to exit 109. 

The northbound off-ramp will also be closed at mile marker 105, but it is scheduled to reopen at 5 a.m. Monday. When that opens, drivers will use the newly built overpass bridge while the on-ramp detour is in place. 

Expect lane closures throughout the area on weekdays from 8 p.m. to 7 a.m. The speed limit will be reduced to 60 miles per hour in the work zone. 

The project is projected to be complete in December 2020.
