Abstract

Expressway managed by NEXCO Central Nippon runs a total distance of approximately 2,100 km and around 60% of the expressway has been open for 30 years or more. In particular, all routes on the Tomei Expressway and Meishin Expressway, which link the east-west axis of the Greater Tokyo Area, the Tokai Area, and the Kansai Area, have been open for 50 years. These two expressways, managed by NEXCO Central Nippon, have aged significantly among expressways nationwide. We have been working on an Expressway Renewal Project that includes replacing bridge decks in order to keep expressways, which are an important transport infrastructure, in a sustainably good condition, while also to maintain a much safer and more comfortable expressway space.
