Major Traffic Signal Upgrades Planned for Round Lake Boulevard in Anoka County

ANOKA COUNTY, MN — November 9, 2025 — A major infrastructure improvement project is set to bring new traffic signals, safer pedestrian crossings, and smoother pavement to a busy stretch of Round Lake Boulevard (County State Aid Highway 9) in Anoka County.

The project—led by Anoka County in partnership with the Cities of Andover and Anoka—will reconstruct and upgrade aging signal systems, modernize pedestrian facilities, and rehabilitate pavement along the corridor from 135th Avenue NW (Roosevelt Street) to 149th Lane NW.

Project Scope and Details

The improvements target six intersections along Round Lake Boulevard between 135th Avenue NW and 143rd Avenue NW:

• Full Signal Reconstruction: 135th Avenue NW/Roosevelt Street, 136th Avenue NW, Bunker Lake Boulevard (County Highway 116), and 138th Lane NW.
• Signal Revisions: 140th Lane NW and 143rd Avenue NW.
• Safety and Accessibility Enhancements: New Flashing Yellow Arrows (FYA) for safer left turns, Accessible Pedestrian Signals (APS) with audible cues, and ADA-compliant pedestrian ramps to improve accessibility for all users.
• Pavement Rehabilitation: A mill-and-overlay project from Bunker Lake Boulevard to 149th Lane NW will extend pavement life, improve ride quality, and support long-term mobility along the corridor.

According to Anoka County officials, the signal upgrades are designed to improve safety, enhance traffic flow, and align with state and federal accessibility standards.

Timeline and Coordination

Construction is anticipated to begin in spring 2026, pending final design approvals and coordination among local jurisdictions. The improvements will coincide with nearby transportation investments—including the Minnesota Department of Transportation’s (MnDOT) ongoing Highway 10 reconstruction between Hanson Boulevard and Round Lake Boulevard, which includes bridge repairs and interchange improvements continuing through 2026.

Public Engagement and Updates

Anoka County encourages residents, businesses, and commuters to stay informed through its “Construction Weekly” publication and project webpage, which provide regular updates on construction schedules, lane closures, and traffic impacts.

The project is part of the county’s broader strategy to maintain roadway durability, enhance traffic operations, and improve safety for motorists, cyclists, and pedestrians across the region.
