- two left-turn lanes on the southbound I-5 on-ramp from westbound State Route 531 (SR 531)
- one left-turn lane on the northbound I-5 on-ramp from eastbound SR 531
- two westbound thru-lanes on SR 531
- one eastbound thru-lane on SR 531
- two left-turn lanes on the northbound I-5 off-ramp to westbound SR 531
- one right-turn lane on the northbound I-5 off-ramp to eastbound SR 531
