84th Street NE corridor safety work starts with lower speed limit

Why it matters

The corridor is a busy east-west route for drivers moving between Marysville, Lake Stevens and Granite Falls, and the work will change both speed expectations and roadside signage.

What happened

The county announced a spot-improvement project that lowers the speed limit from 50 mph to 40 mph and adds warning signs, rumble strips and striping changes.

The details

• The project area runs along 84th Street NE between State Route 9 near Marysville and State Route 92 near Granite Falls.
• The county says the speed limit will be reduced from 50 mph to 40 mph.
• Planned work includes radar feedback speed-limit signs, intersection-ahead signs, flashing traffic-stopped-ahead signs, flashing signal-ahead signs and upgraded street-name signs.
• The project also includes rumble strips, wider fog lines and narrower lane widths.
• The county described the work as safety enhancements intended to reduce speeds and improve signalization and signage.

What's next

Drivers should expect work along the corridor through August 2026 and watch for the new 40 mph speed limit and construction activity.
