a street with telephone poles one right after another
「電柱が続く道」は
a road with telephone poles as far as you can see
a street with telephone poles one right after another
のように言えます。
as far as you can see で「見える限り」
one right after another で「次から次へと・続け様に」
例:
The road I took to school when I was a little boy had telephone poles all the way along it.
「少年の頃学校に行くのに通った道は、道に沿ってずっと電柱が並んでいた。」
