The state says the theft of copper from pumping stations used to clear water from Detroit-area freeways may have been a contributing factor in this week's major highway flooding. Michigan Department of Transportation spokeswoman Diane Cross says an investigation is ongoing to evaluate what went wrong Monday on area roadways. The state says aging infrastructure and pumps that were overwhelmed by the rainfall also are factors. A final determination isn't expected to be made until after the mud, trash, abandoned vehicles and other debris gets cleared. Meanwhile, officials say stretches of Interstates 75, 94 and 696 were still shut down early today along with a stretch of the Southfield Freeway. Michigan Department of Transportation crews are working to reopen the roadways as soon as possible. The storms dumped more than 6 inches of rain in places. Here are some photos from Getty Images that show how bad the flooding is in some areas:
