State Highway 83 (SH 83) is a state highway that is located along the Front Range in the U.S. State of Colorado. Spanning about 56.2 miles (90.4 km) from the SH 21 interchange in northern Colorado Springs and SH 2 in Denver, the highway follows a south–north route, paralleling Interstate 25 to the east and serving rural areas. Along with I-25, it is one of the only two routes in the Colorado State Highway System that directly connects Denver and Colorado Springs.

State Highway 21 (SH 21), also known as Powers Boulevard, is an expressway in El Paso County, in eastern Colorado Springs. SH 21 currently extends from SH 16 in Fountain at its southern end to Interquest Parkway/SH 83 in the north side of Colorado Springs. Extensions to I-25 near North Gate Boulevard are in progress, and extensions south to I-25 near Pikes Peak International Raceway are proposed, and the road is planned to be converted to a freeway in the long-term future.
