RIVERTON, Wyo. (AP) — People are paying higher sales taxes in at least two Wyoming counties to raise money for construction projects.

Fremont County's sales tax increased from 4 percent to 5 percent on Monday.

The Associated Press reports that voters approved the increase in November to pay for infrastructure work such as roads, sewers and water lines. Some items, including groceries, are exempt.

Shoppers in parts of Sweetwater County also began paying higher taxes Monday to raise $81 million in construction projects. The Rock Springs Rocket-Miner says the money will pay for work at Memorial Hospital and Castle Rock Hospital as well as infrastructure work in Granger, Superior, Wamsutter, Green River, Rock Springs and the county.
