You may see a new tool being used to fight snow on area highways this winter. The
Washington State Department of Transportation Eastern Region maintenance crew will be using an innovative “tow plow” on
several highway sections for the first time. A tow plow is a plow mounted on a trailer pulled behind a standard truck-plow. When the operator needs to plow two full lanes the tow plow is maneuvered to the right. The trailer wheels shift to skew the trailer at an angle then the blade drops down, doubling the width of the plowing operation.
This saves time and fuel by being able to clear two lanes, or a lane and shoulder, in a single pass with one vehicle. The tow plow also has a hopper and spreader that can place sand or de-icer at the same time.
The new unit will be based in the Spokane area and primarily used on Interstate 90, US 395, and the North Spokane Corridor. This is the first tow plow operated by WSDOT.
