SEATTLE — More than a hundred goats have descended under the Interstate 5 Ship Canal Bridge, using four-hoof drive to clear vegetation from the right of way.
The voracious eaters, hard at work for the Seattle Department of Transportation, began Sept. 23 and will be there through Monday, according to spokesperson Alison Lorenz.
The 115 ungulates are advantageous for the job since they can navigate steep slopes that people and equipment cannot easily or safely reach. They’re also an environmentally friendly alternative to herbicide, Lorenz said.
The Vashon Island company Rent-A-Ruminant is supplying the goats to do the heavy munching.
In the 15 years the company has worked with SDOT, the goats have sampled vegetation across the Emerald City including the Pine Street Hill Climb stairs, the Jose Rizal Bridge and the Alaskan Way Viaduct. In 2007, the University of Washington hired the goats to address a hillside overgrown with blackberry bushes and English ivy.
