However, the plan was changed due to opposition from people living in the neighborhood; therefore, environmental facility zones were provided instead of the side lane, and the number of main lanes between the Kyotanabe-matsui Interchange and the intersection with National Highway Route No. 170 was reduced to one in each direction so that it now supplements the function of the Hirakata Bypass.
しかし、沿線住民の反対運動などもあり、側道部分を環境施設帯に変更するとともに、住宅地の中を通過する京田辺松井ICから国道170号交点までの区間では本線部分も片側1車線に変更し、枚方バイパスの機能を補完するという現在の形になった。
