SR 167 Extension Toll Feasibility Study

Proposed SR 167 extension from Edgewood to Tacoma

In 2009, the Legislature directed WSDOT to conduct a feasibility study regarding tolling for the SR 167 Extension project. Specifically, WSDOT was asked to examine the following:

  • The potential for variable tolling to generate revenue for transportation facilities within the corridor
  • Maximizing the efficient operation of the corridor
  • Economic considerations for future and system investments

WSDOT worked closely with stakeholders from affected cities and jurisdictions, the Port of Tacoma, the Puget Sound Regional Council and the Federal Highway Administration to evaluate six different combinations of construction and tolling options.
