From WSDOT: Good to Go! Customer Update - New ramp at the SR 167/I-405 interchange is now open (3/1/19)

New ramp at the SR 167/I-405 interchange is now open
The new flyover ramp which provides a direct connection between SR 167 and the carpool lanes on I-405 in Renton is now open.

The ramp is restricted to vehicles with two or more people between 5 a.m. and 7 p.m. daily. Between 7 p.m. and 5 a.m. daily, the new ramp is open to all vehicles.

Here are some tips for drivers using this ramp:

  • If you are traveling northbound in the SR 167 HOT lanes as a carpooler, after the HOT lane ends you can stay left to use the new ramp to access the I-405 carpool lane. If you are a solo driver paying to use the HOT lanes and wish to access I-405, you will need to merge to the right after the HOT lane ends and use the existing ramp used today.
  • If you are traveling southbound in the I-405 carpool lane, after using the new ramp, you will be able to decide whether to enter the HOT lane or merge into the regular lanes.

This ramp is designed to improve traffic flow and safety at this critical interchange. Read more here about how to use the HOT lanes.
