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.
An asphalt driveway costs about $2-$5 a square foot, or $1,200-$3,000 for 12'x50' to $31,000-$75,000 for a 12' lane a quarter mile long. A stamped asphalt pattern (typically in the shape of bricks or stones) on a new or existing asphalt driveway can cost $3-$9 a square foot, or $900-$2,700 for 12'x25' or $3,600-$11,000 for 24'x50' for just the stamping. Concrete is a popular, durable and relatively low-maintenance choice for paving a driveway.
