A fire near the old Fruita refinery broke out at just after 6:30 p.m. Sunday.
The fire shut down the highway for two hours but things now seem to be under control but last night was another story.
Four agencies responded to a brush fire between Fruita and Loma.
At that time, the blaze grew to 30 acres, and law enforcement officials had to shut down I-70 for about two hours.
I-70 did eventually reopen, and firefighters worked through the night to continue to put out flames and monitor hot spots.
There were no injuries reported, and no structures burned, according to Grand Junction Fire Department spokesman Mike Page.
