"Corrugated" and Reflective Striping
May 2013 update: Striping crews are back on the road. Work is highly weather dependent; damp weather will cancel work. Expect to see crews working on the following roads until the end of the month:
Centerlines and edge lines on 67th Ave (from 108th St. to Marysville city limits)
Centerlines on 311th Ave (Ben Howard Road) south of Sultan
NEW: Check out photos (and video) of crews applying corrugated striping on our Flickr page.
Project Description
In fall 2012, a contractor working for Snohomish County began applying
152 miles of corrugated/reflective striping along 38 miles of the following
roads, in the following order:
- Ben Howard Road, between Monroe and Sultan
- Jordan Road, between Granite Falls and Arlington (completed spring 2013)
- Pioneer Highway (north and south of Stanwood - completed spring 2013)
- 45 Road (west of Marysville)
- 67th Avenue NE (between Marysville and Arlington)
Crews completed work along Ben Howard Road and part of Jordan Road, and will return in spring 2013 to complete striping along the other roads. This project is highly weather dependent.
Traffic impacts
Crews will first stripe the center lines, then the edge lines on one side of each
road, then the edge lines on the other side of each road. This method will
prevent a shutdown on any of the roads, but drivers should expect delays.
NOTE: During striping, orange cones will block each driveway for approximately
45 minutes to allow the paint to dry. If you drive over wet paint, you could get paint on your vehicle.
Project benefits
Snohomish County received a $1.7 million federal safety grant to address the problem of vehicles drifting out of lanes or off the road in rural areas. Crews will use the grant to apply reflective "corrugated" Methyl Methacrylate (MMA) striping along the centerlines of the roads. The "corrugated" striping will also be applied on the outside edges of the roads where there are sharp curves. Smooth MMA striping will be applied along most of the outside edges of the roads.
Reflective MMA striping with "corrugated" raised ridges is applied so that drivers feel a rumble effect when vehicles stray out of their lanes.
A national study in 2008 found that 60 percent of all traffic fatalities were caused by vehicles leaving the roadway or veering into oncoming traffic. "Corrugated" striping has a higher profile, is more reflective at night and in wet weather than smooth striping, and more clearly shows the centerlines and edges of a road.
MMA striping also has a longer life expectancy than traditional paint and is more resistant to snowplow damage. The county is using this striping on roads that have a history of crossover or run-of-the-road collisions.
