I noticed today, when doing a yoyo on the Shindian R. bikepath (from Bitan down to the mouth of the Shindian R. and back) that the bridge to connect the upper and lower, north bank, bikepaths at the bottom of Jingmei Park is almost completed. It's two arched, concatenated bridges. When completed, riders will no longer have to go to the top of Jingmei Park, cross Jingmei stream on Shuen An Rd., and go back down to the north bank Shindian riverside bike path. The alternative to the Shuen An Rd. detour is to cross to the south bank bike path, and then ride one of the bridges back to the north bank.
The south bank bike path has fewer stray dogs (I saw none today, whereas there are several packs of strays on the north bank near the mouth of the Xindian R.) and the south bank has far less traffic than the north bank bike path, but if you want to be on the east bank Danshui R. bikepath, you don't want to be on the south bank Xindian R. bike path at the mouth of the Xindian R.
