Hi, Simon,
Good morning, I am Elian from Top China Travel, and have received your message about bus fare to Zhujiajia Water Town from Shanghai Stadium.
The Shanghai Stadium has a shuttle bus every day, depart every at about 30 minutes from 7:30 am to 11:10 am and the last return bus at 16:00 pm. The bus is a tourist bus, which drive on the viaduct and non-stop to the end. It is faster and more comfortable. The bus fare is 12 yuan for a single trip, but it may be changed. Hope this can help you.
If you have a plan to make another tour, you are welcome to book our tour service.
Wish you have a nice day!
Elian from TCT
