"As was expected with one of the oldest and busiest streets in the history of Alton, the contactor has encountered some challenges since excavating started on 3rd Street," Illinois-American Water said again this week. "There are numerous old, abandoned utility lines, and even an old brick cistern was uncovered last week. To support safety, progress has been slowed some, resulting in a bit of a delay."

Illinois American anticipates it will finish the 3rd Street part of the project in a few weeks, then Belle Street shortly after that.
