US-18 runs through 3 states, and each one publishes its cameras on its own website. To follow the whole route you would normally open 3 different sites. Roadze puts the 58 of them together, in the order you actually drive.
Every camera in US-18 was checked today. 58 are listed as working. Roadze re-checks every camera daily against its transportation department, so a camera that goes dark disappears from this page instead of sitting here as a broken thumbnail.
Common questions
How many traffic cameras does US-18 have?
Roadze lists 58 public traffic cameras for US-18: 13 stream live video and 45 are still images that refresh on their own. They all come from the transportation department that runs the road, and they are the same feeds those agencies publish.
Which states does US-18 run through?
US-18 has cameras in 3 states: South Dakota (38), Wisconsin (11) and Iowa (9). Each state runs its own cameras, so the picture quality and how often they refresh change when you cross a state line.
Are the US-18 traffic cameras free to watch?
Yes. Every US-18 camera is public and free, with no account, no app and no limit on how long you watch. Roadze puts them on one map so you do not have to know which agency runs which road.
