这句句子如何理解

Thames, and along the road heading north-east from London to the coast - consist of farmland with crops and livestock which helped to feed that population.
到底是泰晤士河沿着路通向 还是泰晤士河和沿着泰晤士河的路通向？

Answer 1

what's now the East End - the area by the river Thames, and along the road heading north-east from London to the coast - consisted of farmland with crops and livestock which helped to feed that population.
原句是这样的，前文可以知道east end就是 the area by the river Thames,所以and后面的指的只有沿着泰晤士河的路。
仅供参考

Answer 2

应为泰晤士河和沿公路从伦敦向东北方海岸组成的作物和牲畜的饲料，这有助于人口耕地。

了解知识点和语法要点为主，翻译不是很重要。
如：动名搭配 feed...population
help近义表达有support/ assist/ aid
eed近义表达有cater for/ provide for/ nourish/ supply/ nurture

Answer 3

泰晤士河和沿着泰晤士河的路通向
