SANFORD – The Michigan Department of Transportation (MDOT) has announced the closure of US-10 from May 30 through June 6 to allow for the removal of beams on the M-30 bridge over US-10 in Sanford.
The beams, which were installed earlier this month as part of the bridge reconstruction, have begun to show signs of cracking. As a precautionary measure, MDOT is closing US-10 to ensure crews can safely remove and replace the compromised beams.
“Our inspectors discovered cracking in these recently installed beams,” said Jack Hofweber, Mt. Pleasant Transportation Service Center manager. “We made the decision to have them removed and replaced. We will continue to investigate how this occurred, but fortunately, the issue was identified before it posed a danger to the traveling public.”
Both directions of US-10 are now closed and are expected to reopen by Friday, June 6. Westbound US-10 traffic is being detoured via northbound M-30, westbound Curtis Road, and southbound M-18 back to US-10. Eastbound traffic is being rerouted via northbound M-18, eastbound Curtis Road, southbound M-30, eastbound Shaffer Road, and southbound Stark Road back to US-10.
In addition, M-30 remains closed over US-10 for the duration of the project. Southbound M-30 traffic is being detoured via westbound US-10, southbound W. River Road, and eastbound US-10 back to M-30. Northbound traffic is detoured via eastbound US-10, northbound Stark Road, and westbound US-10 back to northbound M-30.
The M-30 bridge replacement is part of a $7.3 million investment aimed at improving the structure and ensuring long-term safety and reliability.
