Highway 10 Expansion in Coon Rapids Nears Completion: Third Lanes to Open by November 21

COON RAPIDS, Minn. — After months of major construction and traffic adjustments, the Minnesota Department of Transportation (MnDOT) has confirmed that the long-awaited third lanes in each direction along Highway 10 in Coon Rapids are scheduled to open to traffic by the end of the day on Friday, November 21.

The update, shared by the City of Coon Rapids Local Government, marks a major milestone in MnDOT’s ongoing efforts to modernize the heavily traveled Highway 10 corridor—a critical east-west route linking communities across Anoka County and the Twin Cities metro area.

Final Construction and Lane Adjustments

As crews prepare for the final phase of construction, MnDOT has released several key updates and timeline details that drivers should note:

• Ramp Closure: The ramp from westbound Highway 10 to Main Street will remain closed until Sunday, November 16, due to delays caused by powerline relocation work.
• Loop Closure: The southbound Round Lake Boulevard loop to eastbound Highway 10 will stay closed until late November as crews complete pavement and barrier installations.
• Week of November 10: Expect single-lane closures during off-peak hours for overhead sign installation along the corridor.
• Week of November 17: Traffic will be shifted so workers can stripe and finalize the new three-lane configuration in both directions.
• Ongoing Work: Construction of noise walls will continue—weather permitting—along eastbound Highway 10 from Main Street to Coon Creek, temporarily reducing eastbound traffic to two lanes during off-peak times.

Modernizing Mobility and Safety

Once complete, the Highway 10 expansion will improve traffic flow, commuter safety, and regional connectivity, easing congestion through one of the metro’s busiest suburban corridors. MnDOT officials have emphasized that this upgrade is part of a broader initiative to improve travel efficiency and safety in the northwest metro area, accommodating both current and future growth.

The three-lane expansion is also expected to reduce travel delays, enhance emergency response access, and minimize bottlenecks at major intersections such as Main Street and Round Lake Boulevard.

Community Impact and Next Steps

For local residents and daily commuters, the completion of this project represents both relief and renewed accessibility. Businesses along the Highway 10 corridor have weathered months of lane reductions and detours, but city officials say the improvements will deliver long-term benefits to Coon Rapids’ transportation infrastructure and economic vitality.

Drivers are urged to stay alert, follow posted detours, and watch for crews as work wraps up through late November.
