Where does the Suiman Expressway go from and to?

[StTanner]

This expressway runs from Suifenhe City to Manzhouli City. Checking the starting and ending points by number: If you frequently drive on expressways, you may notice that different expressways have different numbers. If you are unsure about the starting and ending points of an expressway, you can simply look up its number. Regarding speed limits on expressways: The general speed limit on expressways is 120 kilometers per hour. When driving on an expressway, do not exceed the speed limit, as it can be very dangerous. Expressways also have minimum speed limits. Driving below the minimum speed limit on an expressway is equally hazardous and may lead to severe rear-end collisions. When driving on an expressway at night, you can use high beams because expressways have median barriers, so using high beams will not affect the vision of oncoming drivers.
