I was trying to translate this song, it was all going well until I stumbled
upon this line

> 二人迷わぬよう歩いていけるたった一つの道標

I am having a hard time spliting the words correctly I feel like it either is
lacking some particles or commas, I'm not really sure... What I could come up
with so far:

> 二人(が)迷わぬよう - It's like both do not hesitate.
>
> 歩いていけるたった一つの道標 I can only walk one more signpost. (lol sounds weird, I might
> be wrong)

So maybe the whole thing should rather be structured like this?

> 二人(が)迷わぬよう、歩いていけるたった一つの道標。 It's like both do not hesitate, (but) I can only
> walk one more signpost.

Thanks in advance!

Ps: This is the last line of one paragraph of the song, so it's a ful sentence
which should hold some meaning alone, also the previous line is talking about
other stuff aswell.

EDIT: The whole paragraph of this song is this:

> 一枚一枚増える色の違う写真めくる様に
>
> 伝えたかった事は今も昔もずっと同じままだよ
>
> 二人迷わぬよう歩いていけるたったひとつの道標.

question
grammar particles
Lack of particles in songs
Could this mean the only signpost which both people can reach by walking
without hesitation? And the insertion of が looks right.

The critical problem here is wrong parsing:

> ［二人（が／で）迷わぬよう（に）歩いていける］たった一つの道標  
>  _(It is) the only signpost [that enables us (two) walk along (in pair)
> without(=the way not) losing our way]_

It's a typical "gapless" relative clause explained in [this
topic](https://japanese.stackexchange.com/q/14541/7810). The literal
translation would be "the only one signpost that/where we can walk along..."
but it doesn't make sense in English, I guess. This construction tells
"signpost" has something to do with "we can walk along without being lost",
thus results in the translation above.

For lack of particles, you can insert が or で after 二人 (it's ambiguous whether
it means "we two" or "in two of us"). You can also add に after よう, but it
doesn't change the meaning in this context.

> 「二人迷{ふたりまよ}わぬよう歩{ある}いていけるたった一{ひと}つの道標{みちしるべ}」

First of all, this is only a relative clause, not a sentence of any kind.
Everything in front of 「道標」 modifies 「道標」.

If a somewhat long phrase ends with a noun, there is a big possibility that it
is a relative clause and not a sentence.

Second of all, even though no particles are "lacking" in the first place, let
us add a couple if that helps.

> 「二人（ **が** ）迷わぬよう（ **に** ）歩いていけるたった一つの道標」

If one blindly believes that this is a sentence, trust me, one's translation
is bound to look at least weird or awkward because it is not a sentence to
begin with. Since it is a relative clause, a good TL will have to start with:

> "the only road sign (← 道標) that/which ~~~~~~~~~~"

My own TL would be:

> "the only road sign that enables the two of us to continue walking without
> getting lost"
