Are these sentences correct?

please can anyone help double check and correct the following two sentences?

The fist sentence is:

One Origin, one destination, it's often the route inbetween becomes confusing.

The second sentence is:

One origin, one destination, it's often the route inbetween in which we can make great impact.

What I am trying to express in the first sentence is that the origin and destination are clear, but often the route between these two points are making people confusing.

And in the second sentence I'm trying to say that the origin and destination are not changed, but we can adjust the route between these two points to make the journey a bit more easier, therefore, create a better experience, and give a positive impact.

Thanks
