SNOHOMISH COUNTY— One of Snohomish County’s busiest corridors will get a facelift of sorts beginning this month with safety enhancements designed to reduce speeds and improve signalization and signage. The 84th St NE Corridor Spot Improvements Project, between State Route 9 near Marysville and State Route 92 near Granite Falls, will start May 26 and last through August.
The speed limit along the corridor will be reduced from 50 mph to 40 mph. Road workers will install radar feedback speed limit signs, intersection ahead warning signs, flashing traffic stopped-ahead warning signs and flashing signal-ahead warning signs, and installation of upgraded street name signs. Work will also include installation of rumble strips, establishing wide fog lines, and reducing lane widths.
The speed limit will be further reduced in work zones to 25 mph during county chip-sealing operations that are scheduled to take place in July. The total project cost is $1.43 million and is funded through the Washington Highway Safety Improvement Program.
On a given day, up to 14,000 average daily trips take place along the corridor between SR 9 and SR 92. More than half of the collisions that happen along 84th St NE are near intersections and driveways. Around one-third of all collisions and one-third of injury collisions have been due to speeding or following too closely.
The improvements project is a continuation of the county’s efforts to improve safety in the corridor. A new roundabout opened in 2024 at 84th St NE at 163rd Ave NE. The county is planning to construct another roundabout at 84th St NE and 123rd Ave NE in 2027.
