The Washington State Legislature has stated that tolling should be used when it can contribute a significant portion of the cost of a project that cannot be funded solely with existing sources and/or to optimize the performance of the transportation system.
As a result, WSDOT is often asked to study various potential aspects of tolling a facility. Tolls can generate revenue to help finance future improvements along a corridor as well as help alleviate congestion by making our roadways operate more efficiently.

The Washington State Transportation Commission has also done a number of studies about tolling which can be found on their website.
