[3] Eads was established in 1887 as a railroad town and was named after James Buchanan Eads, a structural engineer with the Missouri Pacific Railroad, who designed and built the Eads Bridge over the Mississippi River at St. Louis in 1874 and went on to design and build the system of levees on the Mississippi Delta which made the river navigable by ocean-going vessels.

Since 2007, there is an annual event where the local businesses of Eads are supported called the Maine street bash; it includes many activities and live performances.

[8] At the 2020 United States Census, the town had a total area of 306 acres (1.237 km2), all of it land.

[5] As of the census[11] of 2000, there were 747 people, 320 households, and 193 families residing in the town.

35.6% of all households were made up of individuals, and 20.3% had someone living alone who was 65 years of age or older.

Partially because of its small size, Eads High School was the first high school in the state of Colorado to provide notebook computers for each of its students and to move to a computer-based curriculum.
