What do interstate signs look like

State, Territorial, County and Secondary highway systems have a lot more variability in standards, capacity and quality, but also sign design, allowing different regions to approach signage in different ways. Some shields, as in Colorado, fully integrate relevant regional graphics like the state flag. In other cases, like Alaska, New Mexico and South Carolina, individual flag elements are incorporated. Arizona, Nevada, Idaho and others show the outline of the state itself in varying detail.

Still others feature simple geometric shapes, like the circles found in New Jersey, Kentucky, Mississippi, Iowa and Delaware. Some states also have secondary highway systems to supplement the main one, usually for a specific purpose, like farm-to-market roads in Texas and connecting links as well as recreational highways in Nebraska.

A Missouri subsystem was created to provide access to most farm houses, schools, churches, cemeteries, and stores within the state. Virgin Islands all have different shapes and colors as well. These designs are not static, either. Many have changed over the decades note: not all of the s-era examples above were actually black-and-white, though overall the shields did feature less color.

Some have retained their essence over time, but others, like New Mexico and Minnesota, have been radically revamped.
