McHENRY – The McHenry Public Works crew spent Wednesday morning repairing a water main break on Park Street. City officials asked residents to avoid Park Street between Elm Street and Venice Court in McHenry after crews were alerted to the break about 7:30 a.m., Utility Division Superintendent Steve Wirch said. Crews fixed the break by 11 a.m., and the roads reopened. Wirch said water main breaks are common this time of year because cold temperatures freeze the ground and the ground shifts. Crews used a stainless steel clamp to fix the break, Wirch said.
