The full story

Paul Wittow, Johnson County engineer, told supervisors the unposted Sutliff Road in the county’s northeast currently defaults to 60 mph under recent statutory changes but should be posted at 55 mph based on a field investigation of road geometry, width, slopes and crash history. "Based off of the results of that investigation, my recommendation would be to set the speed limit at 55 miles per hour," Wittow said while describing the segment from 0.025 Street to the Linn County line.
