Ann Arbor Sinkhole Caused by Leaky Sewer Pipe
ANN ARBOR, Mich. (AP) — Ann Arbor officials say a mysterious sinkhole along a city street is apparently being caused by a leaky sewer pipe.
The sinkhole in the middle of a crosswalk was patched Tuesday by city crews and covered with an orange construction barrel, but additional repairs are planned for Wednesday.
City spokesman Robert Kellar tells The Ann Arbor News (http://bit.ly/2lrKb5B ) the sinkhole is being caused by soil sinking into a hole in a sewer line that’s eight inches in diameter.
Ann Arbor city staff examined the sewer line last Friday and found a hole in that pipe.
The sinkhole had been devouring pavement for days and was about a foot wide when it was paved Tuesday.
Ann Arbor resident Glen Greenlee says there’s been a sinkhole at the intersection for years.
