Second, come out of the North Railway Station exit and go straight without turning until you see a Dicos on the right. Turn right at the street corner in front of it, and then go straight. Go to the intersection where you can cross the road (on your left). You can take bus No.412 at the bus stop there.
Third, it seems that the 4 12 road can't reach Erxian Bridge. The following is the route of 4 12:
Wukuaishi Bus Station-Shiling Bus Station [7:00-20:00] Uninvited ordinary bus 1 RMB bus card invalid bus transportation company.
Wukuaishi Bus Station-North Railway Station-Lotus Pond-Gaosuntang-Huzhu Road Intersection-Liangjiaxiang-First Ring Road North Section-Fuqing Road First Ring Road Overpass-Fuqing Road Second Ring Road Overpass-Fuqing Road Third Section-Bali Community-Xinfeng Road South-Shuangjian Road South-Jianshe North Road Third Section-Factory North Road Intersection-Jianshe Road East-Second Ring Road East-Mashiqiao East Third Section-Mannianba-
Fourth, you should take bus 36 or 402 from North Railway Station to Erxian Bridge. Maybe it's 402? The boarding place is the same as the place above where you take the 4 12 bus.
Fifth, you can see the bus stop sign at the scene. It is recommended to take bus No.36 because there are many cars and the lines are short. Bus No.36 from North Railway Station to Erxian Bridge has only 8 stops, while bus No.402 has 24 stops, which is too roundabout.
