I-84 & SH-21 Webcam in Boise, Idaho

The I-84 & SH-21 Webcam provides a live view of traffic, weather, visibility, and road conditions at one of the most important highway junctions in the Boise area. Located where Interstate 84 meets State Highway 21 in southeast Boise, the camera helps commuters, travelers, and commercial drivers monitor current conditions before entering either route.

Interstate 84 serves as the primary east-west transportation corridor across southern Idaho, while State Highway 21 provides access to the mountains and recreation destinations of central Idaho. Known as the Ponderosa Pine Scenic Byway, SH-21 connects Boise with Idaho City, Lowman, Stanley, and the Sawtooth region, making this interchange a major gateway between the Treasure Valley and Idaho’s backcountry.

The webcam offers a real-time look at traffic flow, roadway conditions, visibility, and congestion levels. Traffic volumes can increase during weekday commute periods as drivers travel between Boise and surrounding communities. Recreational traffic also rises significantly on weekends and holidays as outdoor enthusiasts head toward Idaho’s mountains, rivers, forests, and recreation areas.

Weather conditions can impact travel throughout the year. Winter occasionally brings snow, freezing fog, and icy pavement that reduce visibility and create hazardous driving conditions. Spring often produces rain and changing weather patterns, while summer generally offers favorable driving conditions. During wildfire season, smoke can sometimes affect visibility throughout the region. The webcam provides travelers with an immediate view of current conditions before beginning their trip.

Whether you’re commuting through Boise, traveling east on Interstate 84, or heading north into the mountains on SH-21, the I-84 & SH-21 Webcam provides valuable real-time information that helps improve travel planning and roadway safety.
