I-405/SR-167 Tolling Study
http://www.wsdot.wa.gov/tolling/eastsidecorridor
Proposal to add limited access HOV/HOT lanes, enhanced interchanges and BRT to the I-405/SR-167 corridors.
Not only would this provde an alternative to I-5 for North/South traffic, it would add options to one of the most congested corridors in the state.
