In Minnesota the maximum speed limit of 70 mph (113 km/h) is only allowed outside of urban areas. A speed limit of 55 mph (89 km/h) is typically used in urban areas where a higher speed limit might be used, but traffic congestion or other reasons require a lower speed limit.
Examples include I-94, I-35W and I-35E in and around Minneapolis, Moorhead and Saint Paul. 35E goes down to a speed limit of 45 mph (72 km/h) in some areas of Saint Paul. A speed limit of 60 mph (97 km/h) is typically used in suburban areas such as I-494 and I-694 loops in the Twin Cities metro area.
Non-Interstate divided highways (both freeways and rural expressways) have speed limits of 65 mph (105 km/h) in rural areas and up to 55 mph (89 km/h) in urban or suburban areas. Rural two-lane state and US highways in Minnesota have a default speed limits of 55 mph (89 km/h) although 60 mph (97 km/h) speed limits can be posted after a traffic and engineering study.
County roads have speed limits of up to 55 mph (89 km/h) for two-lanes and 60 mph (97 km/h) for divided sections.
