LaPlaisance Road bridge at I-75 was closed Monday, according to Michigan Department of Transportation.

UPDATE AT 10:49 A.M.

The LaPlaisance Road bridge over I-75 was closed to all traffic Monday afternoon, with Michigan Department of Transportation citing deterioration as the reason.

The map caption on MI Drive says the bridge area is "closed for maintenance" and the closure will end in November 2023.

But a press release that MDOT issued Tuesday gives a slightly different explanation involving deterioration, and a "TBD" or to be determined date.

"The closure allows for an in-depth inspection and subsequent load rating to be performed based on the deterioration found. Any decision to reopen the bridge will be strictly based on the data from inspection and load rating findings," the press release said. This bridge was already scheduled for replacement in 2021, MDOT added.

The posted detours are either to S. Otter Creek Road (Exit 9) or N. Dixie Hwy. (Exit 15).

Highway construction is permitted as essential work under Michigan's "Stay Home Stay Safe" orders during the coronavirus outbreak. MDOT has said its contractors will continue with state projects "when they feel their workers can perform work in a safe manner."

There are multiple areas of I-75 in Monroe County where road projects are in progress. Because of lane closures on I-75's bridge over the River Raisin, the I-75 ramps at Front Street (Exit 13) and Elm Avenue (Exit 14) are closed.

AS OF 8:45 A.M.

The LaPlaisance Road bridge over I-75 was closed to all traffic Monday; and signs have been posted blocking the road.

The closure shows up on the MI Drive website, but it was not sent on the MDOT Twitter or email alerts. In addition, the Michigan Department of Transportation has not issued a news release explaining the situation.

The map caption on MI Drive says the bridge area is "closed for maintenance" and the closure will end in November 2023.
