这条路通向哪里?用英文说

Where does this way lead to?

Which place does this way lead to?

where does this road head?

这两个句子正确
1. 因“Where”是副词，所以lead 后面不需要跟“to”，必须说成：Where does this road head 。
再如：Go home 不说go to home；go there 不说go to there

2.Which place 是名词短语 要用介词to 连接，所以必须说成：Which place does this way lead to?

一楼正确！

where's road heading to ?

Which place does this way lead to?

where does this road head?
