The Odawara-Atsugi Road (小田原厚木道路, Odawara Atsugi Dōro) is a 4-laned toll road in Kanagawa Prefecture, Japan. It is owned and managed by Central Nippon Expressway Company.

Overview

Officially the road is designated as National Route 271.[2] The entire road is built to a standard similar to that of an urban expressway and is classified as a road for motor vehicles only (自動車専用道路, Jidōsha Senyō Dōro) (motor vehicles must have a displacement of at least 125 cc).

The road connects western Kanagawa Prefecture (including the popular onsen resort town of Hakone) with Tokyo through the Tōmei Expressway. The route parallels Route 1 until Ōiso, where it then follows a northeasterly route through Hiratsuka and Isehara before terminating in Atsugi.

The road was opened in 1969 with 2 lanes. Expansion to 4 lanes was completed in 1978.[3]

For toll collection purposes the road is divided into an Odawara section and an Atsugi section, with Ōiso Interchange as the dividing point. The toll for a normal passenger car to use one section is 350 yen.[4]
