Navigate for the driver
From Wuhan to Yichang, it is relatively convenient and expensive to take the Hancai Expressway, and the car costs 20 yuan more. Take Dongfeng Avenue (Zhuankou 3 18 National Road) and Hanyi Expressway to save money when you leave the city. The same is true of entering Wuhan city from Yichang. It is more reasonable and cost-effective for vehicles from Yichang to Zhengzhou and Beijing via Wuhan to take Han Cai Expressway to Beijing-Zhuhai Expressway. It is more reasonable and cost-effective for vehicles from Yichang to Changsha and Zhuhai via Wuhan periphery to take Hanyi Expressway to Beijing-Zhuhai Expressway.
