Speed limits in the United States by jurisdiction
Non-Interstate divided highways (both freeways and expressways) have speed limits of 65 mph in rural areas and up to 60 mph in urban or suburban areas (NOTE: some non-interstate divided highways have gotten speed limit increases in November 2017 such as US Route 169 in the Twin Cities Metropolitan area). Rural two lane State and US highways in Minnesota have a default speed limits of 60 mph although many 55 mph speed limits are still in place after a traffic and engineering study from 2014-2019. County roads have speed limits of up to 55 mph for 2 lanes and 60 for divided sections.
