South of Sanjo Station (Kyoto Prefecture), the street has been extended to Shiokoji-dori Street using the site of the old ground-based Keihan Main Line, which was vacated through the construction of the continuous multi-level crossing of the Keihan Main Line in 1987 between Tofukuji Station and Sanjo Station (Kyoto Prefecture) along the Kamo-gawa River, and the land produced through the construction of a culvert of Biwako Sosui (channel) that is parallel with it.
三条駅(京都府)以南は京阪本線の地上線の跡地であり、1987年に京阪本線の鴨川沿いの東福寺駅-三条駅(京都府)が連続立体交差されたことにより生じた土地と、並行する琵琶湖疏水の溝渠化で出来た用地を使って塩小路通まで延長されている。
