the road either leads from one part to another, or it does not. not a question of future tense: it is always true thus should be declared in present tense (the road will not change tomorrow). The road leads from A to B. Always.
When it comes to me, personally, and my following that road, then yes, the future tense could apply. You could say "that road will lead me from one side to the other". It would lead anyone from one side to the other, actually, if they were to follow it. the road leads, or the road will lead someone, but not the road will lead, unless the road is not actually in existence yet.
