Zhujiajiao Transportation

I prefer to go to Zhujiajiao by public bus instead of the tourist sightseing buses from Shanghai Stadium.
For most travellers, starting from the People's Square area would be reasonable as it's centrally-located. On Pu'an Lu, behind Shanghai Concert Hall, are 2 bus routes that will take you to Zhujiajiao. The nearest metro stop to get here is Dashijie on metro line 8 -- go out of exit no.2 (the one that has a McDonald's), do an about-turn when you reach street level, cross the road in front of you (this is Xizang Zhonglu), keep walking straight and turn right when you get to Pu'an Lu.
Once there, look for a bus route called Hu4 Zhu1 Gao1 Su4 Kuai4 Xian4 (Hu-Zhu Express) -- this is the faster bus that goes by the expressway and gets to Zhujiajiao usually within an hour or so, fare is 12 RMB. The other option is the Hu4 Zhu1 Zhuan1 Xian (Hu-Zhu Route) which's slower and costs 9 RMB -- we took this coming back and I think it took us about almost 2 hours to get back to town! Note that neither bus route has numbers or English, only Chinese characters!
A conductor will come by to buy tickets after the bus starts moving. The express should leave every 30 mins, the non-express bus every 10 mins. However I would venture a guess that they leave whenever full.
Be warned that most of the seats don't have much legroom. If you have long legs, I would recommend that you take the 1st front-facing seats on the same side as the bus doors (ie on the opposite side from the driver), the 1st seats near the back door, or the seats across the 1st seats near the back door (behind the single front-facing seats).
Going from Shanghai to Zhujiajiao in the morning, avoid sitting on the same side as the driver unless you fancy having the sun in your eyes for the entire trip.
