Overview

Officially the road is designated as a bypass for National Route 1. It is also classified as a road for motor vehicles only (自動車専用道路, Jidōsha Senyō Dōro) and access is controlled with interchanges and junctions in a similar manner to national expressways in Japan.

An existing section of the road is also planned to be incorporated into the route of the Ken-Ō Expressway once adjoining sections of that expressway have been completed.[4]

The first section of the road (8.4 km from Fujisawa Interchange to Chigasaki-nishi Interchange) was opened to traffic in 1988. A second section (6.7 km from Chigasaki-nishi Interchange to Ōiso-higashi Interchange) is planned; 1.6 km of the second section was opened to traffic in 1995. Beyond the terminus in Ōiso the road is expected to connect directly to the eastern terminus of the Seishō Bypass.[1]

The toll for a regular passenger car to traverse the entire road is 400 yen. Electronic Toll Collection (ETC) is accepted for payment, however no discount programs are in effect.
