Laiwu North Toll Station, to Jinan Ganggou Toll Station. How many kilometers, how much is the highway charge. How to get down?

I often go this way. Gangganggou is 78 kilometers, and 25 yuan is less than seven blocks. Go north from Changshao North Road. If there is a sign to Jinan, turn left and drive west for more than 40 kilometers after arriving at Zhangqiu National Highway 309. After crossing Xingcun Interchange for 2 kilometers, Ganggou is south. There are two toll stations below, 20 yuan. If you bypass the toll station of National Highway 309, you will enter Zhangqiu city and then go west to century avenue. Personally, I think it is more convenient to take the expressway.
