US-16A Keystone, South Dakota Live Webcam & Road Conditions (MP 56)
The US-16A live webcam in Keystone, South Dakota provides real-time views of traffic flow, surface conditions, and visibility along U.S. Highway 16A, one of the most scenic drives in the Black Hills region. Located at Milepost 56, this camera captures current road conditions near Keystone — a major gateway to Mount Rushmore National Memorial and other iconic attractions.
Unlike US-16, US-16A is a scenic alternate route, winding through forested hills, curves, elevation changes, and granite outcroppings. It carries:
