Washington State Department of Transportation (WSDOT) has been actively building its next Express Lanes facility on I-405. The facility is now in testing mode, and travelers will see visible progress. In implementing the facility, WSDOT is changing some of its policies regarding carpools. This is a similar change to that of Colorado DOT, who is also opening its next Express Lane facility this year with changed carpool policies. Of note and as reported,
- HOV customers must have a “Flex Pass” (switchable transponder) in order to use the lanes for free,
- Motorcycles must have a motorcycle transponder to use the lanes for free, and
- There will be differential HOV policies by time of day. HOV-3+ for peak periods, HOV-2+ for off-peak periods, as outlined here.
