A story on page B2 of Monday’s Sun Journal incorrectly reported the effect of a leaking penstock pipe located on Lisbon Street between Adams Avenue and Bleachery Street. The leak was discovered last week as crews were investigating a pothole at that location. Work repairing the pothole and a cave-in that formed under the road is scheduled to close Lisbon Street at that location through May 12. The work is located about 150 feet north on Lisbon Street from a sinkhole that formed in 2006. Public Services Director Dave Jones said the two sinkholes are unrelated.
