Beginning the weekend of Feb. 4, southbound I-75 will close down for two years.  That's the planned date to begin a major project, rebuild the deck of the I-75 Rouge River Bridge.

Rouge River Bridge, is believed to be at the end of its useful life and has seen massive potholes open up in recent years.  It was built in 1967 and MDOT said it has spent $66 million on maintaining the bridge.

Northbound travel lanes will be maintained during the project, although they will shift in 2018 to the southbound side of the highway as the construction switches sides.

It's expected to add an extra 30-35 miles to the trip downriver and will affect a huge volume of traffic because about 37 million vehicles cross the bridge every year.  Here's more information from the Detroit Free Press.
