Because less distance is traveled between the Seta-higashi Junction and the Oyamazaki Interchange/Junction if drivers take the Keiji Bypass instead of the Meishin Highway, a driver driving at the speed limit on the Keiji Bypass will arrive at their destination more quickly than a driver driving at the speed limit on the Meishin Highway.
瀬田東IC-大山崎IC・JCTの距離は名神高速道路よりも京滋バイパスのほうが若干短く、最高速度通り走行した場合、京滋バイパス経由のほうが早く目的地に行ける。
