Its eastern border is also the state border of Idaho and Wyoming. Idaho Falls, originally called Eagle Rock, is the county seat. Incorporated cities in Bonneville County include Ammon, Idaho Falls, Iona, Irwin, Swan Valley, and Ucon. Bonneville is the fourth largest county in the state with a population of more than 104,000.
As a very loose guideline, in most areas, asphalt installation will range from about $2.50 to $4.00 per square foot, while concrete typically ranges from about $4.00 to about $6.00 per square foot but can rise to more than $15.00 per square foot when special finishes and detailing are used.
Where the average cost per square foot of paved walkway is around $5-$10 per linear foot, including excavation, labor, and base layers, adding features such as a curb can increase that figure. Still, the overall cost of an asphalt walkway is much lower than any other paving project based on its relative size.
