US-16A Highway Webcams

Live Traffic Cameras, Road Conditions & Weather Along U.S. Route 16A

Route 16A is one of the most scenic drives in the Black Hills of South Dakota. This alternate route of US-16 runs between the towns of Custer and Keystone and is widely known as Iron Mountain Road, a winding mountain highway famous for its tunnels, bridges, and sweeping views of the surrounding landscape.

Built during the early 20th century, Route 16A was designed as a scenic highway that would allow travelers to experience the natural beauty of the Black Hills while traveling at a slower pace. Instead of a straight highway, the road curves through forests and granite formations with dramatic switchbacks, spiral bridges, and narrow rock tunnels carved directly through the hills.

Mount Rushmore Views Along Route 16A

One of the most unique features of Route 16A is the series of tunnels that frame distant views of Mount Rushmore. As drivers approach certain tunnels along the route, the opening perfectly aligns with the famous presidential sculpture in the distance, creating one of the most iconic driving views in South Dakota.

Because the highway winds through mountainous terrain and popular tourist destinations, travel conditions can change quickly depending on traffic levels and weather conditions. Rain, fog, snow, and wildlife activity can all affect driving conditions along this scenic Black Hills roadway.
