very nice. Just a couple of small details. The meter on the second to last line of the chorus seems a little off. You might want to try taking the "all" out: "we reach our destinations, one by one".

In the second verse, I was a bit confused by the highway line. Do you mean that they all died in car accidents, or is it "the highway of life"?

Other than that, a very poignant, lovely song.
