RICHMOND, VA (WWBT) - Crews are continuing to fight one of the largest wildfires on the eastern seaboard right now.
The fires in Alleghany and Rockbridge counties are growing so big, fire officials had to bring in fleets from out west to help.
Experts from the United States forest service say these may be the biggest wildfires the commonwealth has seen in roughly 100 years.
The biggest fire right now is the Alleghany tunnels fire northwest of Lynchburg.
It's burned roughly 7,000 acres around Covington, Virginia.
It's so dangerous crews from traveled from Arizona to help the local departments here.
Right now, they're building containment lines to keep it from jumping I-64.
State police closed part of it down Wednesday after a separate fire burned roughly 3,000 acres in Rockbridge County.
Smoke was blowing across I-64, creating dangerous driving conditions for travelers.
Even though it's open now, drivers still want to be cautious of smoke in the area.
The strong winds and little rain have only made things worse.
Fire crews still don't know how long it will take to contain the flames, but they hope to get everything under control in the next couple of days before the fires reach nearby communities.
