MDOT Begins Major US-31 Rebuilding Near Interlochen, Detour Disrupts West Michigan Travel

Michigan Department of Transportation Launches $4.7 Million Project to Rebuild 7.8-Mile Section of US-31 Through Grand Traverse County

The project will require detours through Green Lake Township and Benzie County, potentially affecting residents and tourists traveling between Traverse City, Interlochen, and the Benzie Peninsula.

LANSING — The Michigan Department of Transportation has authorized a major infrastructure project that will reshape travel patterns across Grand Traverse County and Benzie County, affecting thousands of motorists who rely on US-31 as their primary route through the region.

The project involves rebuilding a 7.8-mile section of US-31 from Sullivan Road in Green Lake Township, Grand Traverse County, to Reynolds Road in Inland Township, Benzie County. According to MDOT officials, construction could begin as early as Tuesday, April 7, requiring significant detours through local roads.

Impact on West Michigan Travelers

The detour will force traffic off of the current US-31 alignment, redirecting drivers through a network of local streets that may experience increased congestion. Residents of Traverse City, Interlochen, and the surrounding communities will need to navigate alternative routes to reach their destinations.

Tourism officials in Grand Traverse County express concern about the timing of the project. The area sees heavy tourist traffic during spring and summer months, particularly from visitors heading to the beaches of Benzie County or attending events at the Interlochen Center for the Arts.

"US-31 is the backbone of travel through our region," said one local transportation advocate. "When you take it offline, you're not just affecting commuters — you're disrupting the entire travel ecosystem for our communities."

Project Cost and Timeline

MDOT has allocated $4.7 million for the rebuilding project, which includes reconstruction of road surfaces, drainage improvements, and potential upgrades to bridges and culverts along the corridor. The exact timeline for completion remains to be determined, but officials anticipate the project will span multiple months.

The Michigan Department of Transportation's press release notes that the project addresses safety concerns and infrastructure deterioration that has developed over time. Officials state that the rebuilding effort will bring the roadway up to modern standards and improve long-term durability.

Community Concerns

Local residents in Green Lake Township and Benzie County have already begun voicing concerns about the project's impact on their daily lives. Many families rely on US-31 for commuting to work, attending school, and running errands.

The detour routing through local residential streets could lead to increased noise, pollution, and traffic congestion in neighborhoods that were previously buffered from through traffic. Homeowners association meetings in the affected areas have drawn crowds of concerned citizens.

Economic Implications

The project's impact extends beyond individual travelers. Local businesses along the corridor, including restaurants, retail establishments, and service providers, may experience reduced customer traffic during construction periods.

Tourism-dependent industries in Grand Traverse County and Benzie County face additional challenges. Hotels, vacation rentals, and attractions that rely on easy highway access may see decreased bookings if travelers are deterred by the detour and associated delays.

MDOT Response

MDOT officials emphasize that the project is necessary to maintain safe and reliable transportation infrastructure. The department states that rebuilding US-31 will ultimately benefit all users by providing a more durable and efficient route through the region.

The agency has committed to working closely with local communities to minimize disruption and communicate clearly about detour routing and timing. MDOT has established a dedicated communications channel to answer questions from residents and businesses affected by the project.

Broader Context

The US-31 rebuilding project comes amid a period of increased infrastructure investment across Michigan. State officials have prioritized transportation improvements as part of a broader effort to maintain roads and bridges that serve millions of drivers annually.

However, the timing and scope of this particular project have drawn attention from advocacy groups that argue for more consideration of local impacts. Transportation planners emphasize the need for projects that balance state-level infrastructure goals with community needs.

What Motorists Need to Know

Motorists traveling through Grand Traverse County and Benzie County should monitor MDOT communications for the latest detour information. The department plans to post detailed maps and schedules on its website and social media channels.

Local media outlets in the region are also providing coverage of the project and its impacts, offering additional resources for affected residents and travelers.

The MDOT press release from April 1, 2026, confirms that the project is moving forward with the intention of beginning construction on April 7, requiring immediate detour implementation.
