Tolling Planning

	SR 509 Toll Feasibility Study

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.

Studies currently underway:

• SR 167 Extension Comprehensive Tolling Study
• I90 Tolling Environmental Assessment

• SR 509 Extension Phasing Plan (March 2012)
• SR 520 Investment Grade Traffic and Revenue Study (August 2011)
