Prior to the construction of I-70, the swell was inaccessible via paved roads and relatively undiscovered.

Since I-70's construction the swell has been discovered for its desolate beauty. The swell has since been nominated for National Park and/or National Monument status on multiple occasions. If the swell is granted this status it arguably would be the first time a National Park owes its existence to an Interstate Highway. Most of the exits in this span are view areas

When leaving the Rocky Mountains, the Denver skyline can be seen on a clear day. This can fool truckers and other unsuspecting drivers because there is still over 10 miles (16.1 km) of steep grade road before reaching the city. A series of signs warn truckers of the steep grade.

Coming from Colorado, I-70 enters the prairie, farmlands, and rolling hills of Kansas.
