The Washington State Department of Transportation deployed a goat herd on Monday, June 12, to help mow down vegetation under a Seattle bridge.

The Vancouver-based goats, who were under the Portage Bay Bridge, have less greenhouse gas, are more environmentally friendly, and free up the maintenance staff for other projects, the DOT said. The DOT first used goats to cut back weeds and vegetation in 2015. Credit: Washington State DOT via Storyful
