The speed limit on interstates is 75-80 mph, on US highways 65 mph. Watch for sudden construction zones near Pueblo and Lamar.

The first 75 miles wind through Rocky Mountain National Park's montane forests and meadows, with elk frequenting the roadside near Moraine Park. After descending into Denver, the terrain flattens into shortgrass prairie punctuated by buttes such as Pawnee Buttes (a 4-mile detour northeast of Raymer). The climatological contrast is stark: Estes Park's alpine mornings (40-60°F in summer) transition to Amarillo's hot, dry afternoons (90-100°F). Spring brings tornado risk; afternoon storms are common July-September.
