Mayor Tom Barrett worked with a Department of Public Works pothole-filling crew on Wednesday, May 1 in a northwest side Milwaukee neighborhood. The number of pothole complaints in the city is up this year compared to 2012, due in part to a wet winter and several freeze/thaw cycles. With the recent warmer weather, DPW crews have switched to using hot mix asphalt for filling potholes, which adheres significantly better to the pavement compared to cold mix asphalt used during the winter months. To report a pothole, residents should call 286-CITY (2489).
