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.
The best way to approach cost is to determine the amount of square feet you will need paved. Typically, asphalt driveways can cost anywhere from $3.00 - $6.00 vs concrete driveway which cost anywhere from $6.00 - $12.00 pending the amount of area you need paved.
