HOLLAND, MI (WHTC) - Holland BPW crews should be at work today repairing a broken sewer main in the Holland Heights neighborhood. Utility officials say that increased construction traffic in the area of 8^th Street and Country Club Road last week led to the blockage and collapse of a six-inch pipe. It caused a three-foot-wide, two-foot-deep sinkhole, and sewage was backed up into six basements. Repairs should go through the end of the week.
