Road Construction Near Interlochen: April—June Traffic Changes
The Michigan Department of Transportation will begin a major reconstruction project on U.S. Route 31 this spring near Interlochen.
The project will rebuild nearly eight miles of highway from Sullivan Road to Reynolds Road, with improvements that include additional turn lanes, wider shoulders, rumble strips, and a new roundabout at the intersection of South Long Lake Road and J. Maddy Parkway. Work is expected to continue through November.
The first traffic change affecting Interlochen will occur at the start of construction in April.
Road construction is scheduled to begin April 15 (but could launch sooner if weather allows). During this time:
- Southbound US-31 traffic will be maintained on US-31.
- Northbound US-31 traffic will be detoured on Gonder Road, Riley Road, J. Maddy Parkway, Youker Road, and County Road 633.
- J. Maddy Parkway access to US-31 will be closed for up to two weeks in April while crews build temporary lanes around the roundabout.
- South Long Lake Road access to US-31 will be closed through June, with traffic detouring on West Silver Lake Road and Secor Road.
Additional traffic adjustments will occur later in the construction season, and Interlochen will share updates as new phases begin. For the latest information and detour details, please check out VisitInterlochen.com.
