KINGMAN, Ariz. (AP) — Volunteers help workers, tourists and walkers climbing the hill to Union Pass from Bullhead City toward Kingman fight the desert heat by providing jugs of water along the treacherous road.

Golden Valley resident Carla Lambert said co-worker Kim Hunter started the project about four years ago. Lambert, who has now taken over placing the jugs, got involved after seeing people struggle with the pass while going to and from work, the Kingman Daily Miner reported .

"Over the 25 years I've lived in Golden Valley going back and forth to Laughlin working, I've seen so many cars along the side of the road burn up," she said, which got her thinking. "There's got to be a way for us to get something on the mountain so they don't have to wait until their cars burn up before the fire department gets there."

Without water, an overheated car on fire can cause brush fires, another danger she hopes is reduced by offering water, Lambert said.

In previous years, 400 to 500 jugs have been placed along Highway 68. But this year the project has grown substantially. More than 1,300 water jugs have been placed since the end of April, Lambert said.

Lambert gets the jugs through donations from local businesses and fills them with water from the well at her home. Community members have begun to put jugs out on their own.

Lambert places large garbage cans at the end of her street and by her house in which people can drop off empty jugs.

The water jugs are more often than not used by motorists needing to cool of their engines, but those walking or biking the pass are free to take a drink as well. The jugs are safe to drink because she fills the jugs from her well at home, Lambert said.

"It's for anybody who needs it," she said.
