Development Plan of
High-standard Highways
In 1957, the “National Development Longitudinal
Expressway Construction Law” and “ National
Expressway Law” were enacted, and in 1956 the
Japan Highway Public Corporation was established.
Full constructions of inter-city expressways were
started at that time.
In the “4th National Comprehensive Development
Program” developed in June of 1987, it was
required that construction of 14,000 km arterial
high-standard highway network be constructed in
order to promote “Interaction Network Initiative,” contributing to a multi-polar, decentralized nation for
21st century. This plan, adding 6,220 km of new
routes to already planned national expressway
(7,600 km) and the Honshu-Shikoku Expressway
(180 km) is the same level as European countries,
when compared with population, area, GNP, the
number of automobile ownership and km-vehicle.
Arterial high-standard highways in service at the
end of FY 2004 is 8,730 km. By reducing the
transport time and distance between points
throughout the nation and securing redundancy,
these roads have a substantial impact on the lives
and industries of the cities, towns and villages along
these roads. |
