Drivers are urged to be prepared for significant delays along Fourth Plain Road, from Fort Vancouver Way to Falk Road, while pavement "microsurfacing" takes place from evening through early morning hours, scheduled for next Wednesday evening until early Saturday morning, weather permitting.
To minimize traffic disruptions, the work will take place between 7 p.m. and 6 a.m., over two to three nights. Microsurfacing is highly weather dependent. In the event of rain, it will be rescheduled.
Though Fourth Plain is expected to remain open during the work, drivers should be prepared for significant delays. Driveways and intersections along that section of Fourth Plain will be closed for at least 30 minutes while the operation passes by. Drivers, bicyclists and pedestrians should be alert to flaggers and remain off the treated road surface until given the signal to proceed. Where possible, drivers are encouraged to take a different route.
The work, to be performed by contractor, Intermountain Slurry Seal, Inc., is part of the City of Vancouver's annual Pavement Management Program.
Microsurfacing is a paving system, not the same as asphalt, that begins as a coarse liquid application of aggregate, asphalt emulsion, water and fillers. It is made and applied to existing pavement by a special machine that carries all components, mixes them on site and spreads the mixture onto the road surface. The surfacing is very sticky until it dries a short time after the application. As the product cures, the surface becomes smoother. The finished sealant forms a thin shell over the street's existing asphalt surface, providing a cost-effective maintenance that extends the life of the underlying pavement.
