Proposition 1 on the Airway Heights ballot will ask voters to approve a 10-year, three-tenths of one percent sales tax on goods and services sold within city limits dedicated specifically for road construction. Airway Heights, which nearly doubled in size from 6,100 residents in the 2010 census to 10,757 in 2020, is one of 55 cities statewide that funds what's known as a transportation benefit district through a portion of the sales tax, according to the Municipal Research and Services Center of Washington.
