This is due to the fact that Fushimi, through which the road passes, does not only lead to Nara but serves also as the gateway for land and river transportation to the Osaka area, as well as the fact that the name Takeda-kaido Road had already been established for the present-day National Route 24. 
これはその経路にある伏見は、奈良方面だけでなくかつては大阪方面への陸路・水路の玄関口でもあったこと、また、現在の国道24号の経路は竹田街道という名称が根付いているためである。
