WSDOT snow mode procedures

The Washington State Department Of Transportation, also known as WSDOT, operates and maintains all the highways in the state.

The Washington State Department of Transportation is the steward of a multi-modal transportation system and responsible for ensuring that people and goods move safely and efficiently.

In addition to building, maintaining, and operating the state highway system, WSDOT is responsible for the state ferry system, and works in partnership with others to maintain and improve local roads, railroads and airports, as well as to support alternatives to driving, such as public transportation, bicycles and pedestrian programs.

WSDOT operates and maintains 18,600 lane miles of state highways, 3,300 bridge structures, runs the largest ferry system in the nation that moves 24.2 million passengers and 10 million vehicles a year, partners with 31 public transportation systems to provide more than 220 million passenger trips a year, and owns three Talgo train sets in the Amtrak Cascades fleet and manages the Palouse River and Coulee City Rail system

They work 24/7 during weather advisory days to make sure the roads are safe to drive.

This means that they clear the roadways as best as they can.

The Pacific Northwest was hit with the past couple of days with blizzard like conditions, and WSDOT was prepared with full staff.

Roads were completely covered with snow and cars that drifted off.

Because of the dangerous low visibility conditions in the highways and freeways, WSDOT closed over a dozen roads on Saturday alone.

Roads were either worked on or closed.



SR 24/Moxee-Hanford.

SR 240/Hanford to W. Richland.

SR 225/W. Richland. 

SR 241 North of Sunnyside.

SR 221/Paterson-Prosser.

I-82/Coffin Road to the Oregon border.

I-82 b/n Ellensburg & Sellah.

WSDOT concentrates on the right lane of the main highways during a snow storm.

They say they don't work on ramps as much because their priority is the highways.

During the blizzard like conditions, WSDOT had a plower running on a highway at all times until the weather didn't allow it.

They recommend to keep your distance between vehicles and always carry your chains.

They also advice individuals to pack extra clothes, food and water just in case the highways are closed or if you are stranded.
