Brush fire impacting traffic on I-90 near Vantage

VANTAGE, Wash. -- Crews are working to contain a brush fire that is impacting traffic on Interstate 90 in central Washington.

The Washington State Patrol said the fire near Vantage grew to 1,500 acres overnight but is now under control.

State troopers say one lane of the highway reopened in each direction Monday morning. Fire crews are still using up to one lane of each direction as they work to contain the fire.

It is unclear what caused the fire.

In a separate incident Sunday morning, a semi fire on the bridge across the Columbia River forced the freeway to be shut down for several hours.

This is a developing story and will be updated.
