What do you do when a 200-ton rock renders your road impassable? Blow it up, of course.

The humongous rock fell onto an Oregon highway early Thursday morning, halting traffic and leaving crews with a heck of a cleanup job, according to the Oregon Department of Transportation. Workers exploded the rock, which was on Oregon 138 east of Glide, but there's still plenty to do before the highway is back to normal.

The good news: No one was struck by falling blubber in this latest Oregon explosion.

The state transportation agency estimates one of the highway's lanes will open late Thursday night. Cleanup and paving work will persist through at least the weekend, according to the agency.

ODOT urges travelers to use different routes from Interstate 5 to U.S. 97 during the day Thursday. The agency suggested taking Oregon 58 or 62.
