http://pokemondb.net/pokebase/263691/why-is-sinnoh-route-219-not-a-sea-route?show=263907#a263907 once you make it somewhat relevant to the question. I kind of understand what you're saying, but there is no such thing as a translation error when it literally says "Route 219" and the Japanese version uses different characters too - ばんどうろ (Route) as opposed to ばんすいどう (water Route).
