MUHLENBERG TWP., Pa. -

Last week's polar vortex is wreaking havoc across Berks County. Potholes are popping up all over the county, and road crews say the cold weather is to blame.

"A couple potholes came out on Route 61 here, so we are out repairing the potholes," said Neal Moyer, PennDOT assistant highway maintenance manager, adding that the cold is to blame.

"Last week, it was pretty cold and you have the freezing and the thawing and then water gets down in the road and then the freezing breaks up the road," said Moyer.

Unfortunately, this vicious cycle happens every winter, but Moyer said the extreme cold made it worse this year, and crews are getting calls from all over the county to come and fix roads.

"It has been a lot busier since this past freezing we had. It was not bad before but now it seems to be getting worse," said Moyer.

But until crews can get to your area for repairs, they have some advice for drivers.

"If you do see them, just hopefully slow down, drive around them, try to avoid them and let us know so we can repair them," said Moyer.

PennDOT was out filling potholes along Route 61 all day Monday. The next big project is the Penn Street Bridge in Reading.

If you see potholes, call 1-800-FIX-ROAD to make crews aware of the conditions.
