A water main break caused major issues at Kennywood during its annual “Holiday Lights” festivities last night. Officials said the park did open as scheduled Thursday at 5 p.m. – hours after the water main break – but there was a delay in restoring service. Food stands, among other places at the park, were closed until water was fully restored hours later. Crews were making repairs to the line throughout the day. Officials didn’t say what caused the water main break, but some bathrooms were reportedly unusable, along with several popular food stands. Park attendees said they received vouchers to come back at a later date because of the water main break.
