A Polk County judge is siding with the Iowa Department of Transportation in a case involving automated traffic enforcement cameras. The DOT previously said the highways in Cedar Rapids, Des Moines, and Muscatine weren't made safer by the cameras, so they needed to come down. The cities disagreed, but judge Scott Rosenberg sided with the DOT Thursday. The cameras in question are on Interstate 235 in Des Moines, at three locations along Interstate 380 in Cedar Rapids, and at an intersection in Muscatine on Highway 61.
