Someone raised the suspicion about who chose the route. I'm pointing out that the choice of route was dependent on the destination, and that was insisted on by the governor, who was also a victim.
As for being more than one way to get there, look at a map of Dallas. If you want to go from Love Field to the Trade Mart while having a motorcade down Main St, there really were no choices involved.
I always found it odd, that the motorcade route was so concvenient for Oswald. Didn't he start work there before the trip was planned ot at least before the route was known? Or is it alleged that he heard about the route and then decided to take advantage of it?
Was it a coincidence or just some quirk of fate?
