I-405 - SR 167 Interchange Direct Connector Project - HOV ramp operations

The new HOV ramp provides a direct connection between SR 167 and the carpool lanes on I-405 in Renton.

The HOV ramp has the same operations as the I-405 carpool lanes and 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.

How to use the HOV ramp

From northbound SR 167:

  • Carpoolers need to be in the left lane after the high occupancy toll (HOT) lane ends if they want to use the HOV ramp connecting to the I-405 carpool lanes.
  • Similar to today, solo drivers paying to use the HOT lanes and wanting to access I-405, need to merge to the right after the HOT lane ends and use the existing on-ramp.

From southbound I-405:

  • Carpoolers traveling in the southbound I-405 carpool lane and using the HOV ramp can either enter the HOT lane or merge into the general purpose lanes.
