Wausau drivers will have to avoid a section of Third Avenue for a few days, as the flood waters continue to wreak havoc.
A section of the road is sinking.
The problem area is at the corner of Third and Wausau, where the storm sewer underneath the concrete has washed away.
"Rainwater in the storm sewer, which is a pretty busy storm sewer, it handles a lot of the neighborhood west of here, drains it to the Wisconsin river, that man hole washed away so that water has no control," said Brad Marquardt, Wausau's director of public works and utilities.
Marquardt says the area of the street that's affected has about a 30 to 40 foot diamter.
Now crews will rip off the concrete to reinstall the storm sewer.
The section of the street between Union and Norton Streets could be closed several days.
