A trailer caught fire on the Redmond Way ramp to westbound State Route 520 on Wednesday afternoon, halting traffic on the ramp and causing delays on 520.
Shots from WSDOT cams showed heavy black smoke and flames coming from the trailer. Fire crews quickly arrived and managed to put the fire out within minutes.
WSDOT officials said everyone was able to get out of the vehicle OK. No injuries were reported.
Drivers were advised to expect the ramp to remain closed until the trailer was removed from the ramp.
