The Michigan Department of Transportation announced on April 1 that it will begin an $80,000 project to replace the guardrail on the M-24 bridge over the Flint River in Mayfield Township, Lapeer County. The work is scheduled to start Monday, April 6 and is expected to finish by Friday, April 10.
The project aims to upgrade the existing guardrail so it meets current safety standards. Traffic will be maintained along M-24 using a flagging operation during construction. According to MDOT, this effort is part of a broader initiative across its Bay Region to update aging guardrails for improved safety.
The Michigan Department of Transportation manages nearly 10,000 miles of state highways and more than 4,800 bridges throughout Michigan according to the official website. Its responsibilities also include overseeing non-motorized trails, railroad tracks, and various airports statewide.
With more than 2,800 employees working across seven regions and numerous facilities according to the official website, MDOT’s operations cover a wide range of transportation infrastructure needs. The department maintains all state highway systems—including M routes like M-24—as well as interstate and US routes while also managing bridge maintenance and safety standards according to the official website.
Leadership at MDOT includes a director supported by key executives such as chief administrative officer and chief operations officer according to the official website.
