The Keiji Bypass is a four-lane dual-carriageway that begins at Seta-higashi Junction in the city of Ōtsu in Shiga Prefecture. From here it curves to the southwest to bypass Kyoto. It goes through several tunnels as it crosses in to Kyoto Prefecture. To the south of Kyoto, it is paralleled by National Route 1 and further to the west, National Route 478. Its western terminus is at the Meishin Expressway to the southwest of Kyoto. The roadway of the Keiji Bypass continues on to the northwest as the Kyoto Jūkan Expressway.[2] The entire route has a speed limit of 80kph.
The Keiji Bypass is a direct extension of National Route 1. Therefore, the distance markings continue from the sequence of Route 1, starting at 479.3km (297.8miles) at Seta-highashi Interchange. TB= Toll booth|colspan="8" style="text-align: center;"|Through to Kyoto Jūkan Expressway
