Traffic has been moving slowly on southbound I-475 Thursday evening.
The highway has been reduced to one lane between State Route 65 and State Route 25 near Perrysburg.
We're told O-DOT is working to make pavement repairs after a large pothole developed.
The work was expected to be complete by 8:00 p.m., but because of cold temperatures, a spokesperson says the lane will remain closed at least through 6:00 a.m. Friday morning.
