Officials say road crews are on track to finish rebuilding a large bridge over Interstate 75 by the end of 2018.
The Detroit News reports the Michigan Department of Transportation this week gave an update on the Rouge River bridge project.
The southbound lanes of I-75 have been closed for about 8 miles (13 kilometers) from Detroit to Southgate since February for construction.
In mid-November, work will take place in the northbound lanes.
The $220 million project is replacing concrete on the bridge, which carries 37 million vehicles per year, and replacing or repairing 13 other spans.
The Rouge River bridge originally was built in 1967 and the bridge deck had deteriorated to the point of needing replacement.
